PLANTS   BAKERIAN^E. 


Under  the  above  title,  for  the  purpose  of  citation  easily 
abbreviated  to  PL  Baker.,  it  is  proposed  to  issue  a  series  of 
lists  of  plants  collected  by  Mr.  Carl  F.  Baker  and  his  col- 
leagues and  distributed  to  various  herbaria  on  both  sides  of 
the  Atlantic. 

The  first  volume  of  these  Catalogues  will  include 
the  collections  of  1898  by  Messrs.  C.  F.  Baker,  F.  S. 
Earle  and  S.  M.  Tracy  in  Southern  Colorado.  The  sets 
were  distributed  nearly  two  years  since,  and,  as  regards  the 
flowering  plants,  under  names  in  a  very  great  many  cases 
far  from  correct.  Nearly  all  were  subsequently  submitted 
to  me  for  determination ;  and  this  list,  in  so  far  as  I  have 
edited  it,  will  be  approximately  correct  as  to  the  identity 
and  nomenclature  of  the  species.

In  planning  a  botanical  collecting  trip  to  Southwestern 
Colorado  our  objects  were  first,  to  secure  sets  of  plants  rep- 
resentative of  the  flora  of  this  interesting  region ;  and, 
second,  to  study  in  the  field  the  effect  of  altitude  and 
exposure  on  the  variability  and  the  distribution  of  species. 
It  was  at  first  hoped  that  we  might  be  able  to  examine  some- 
what critically  the  La  Plata  Mountains  in  the  extreme  South- 
western part  of  the  State,  and  also  considerable  portions 
of  the  larger  neighboring  range  of  the  San  Juan.  Lack 
of  time  prevented  carrying  out  the  latter  plan,  the  work 
being  confined  exclusively  to  the  La  Plata  Range,  and 
the  neighboring  lower  levels.  The  region  proved  ad- 
mirably adapted  to  the  purposes  of  the  expedition.  The 
Range  is  isolated,  and  though  small  in  area  is  of  consider- 
able altitude,  the  central  peak,  Mt.  Hesperus,  holding  its 
rugged  snow-streaked  crest  at  the  height  of  13,300  feet.  As 
seen  from  the  west  this  mountain  presents  a  peculiar  and 
fantastic  appearance.  The  portion  above  timber  line  is  a 
regularly  outlined  rock  pyramid  formed  of  nearly  horizontal 
strata  of  various  colors  giving  a  curious  banded  effect ;  while 
numerous  gulches  filled  with  snow  mark  it  with  vertical 
lines  of  white.  Mt.  Hesperus  is  flanked  and  supported  on 
the  North  by  Shark's  Tooth,  a  pinnacle  of  rock  well  deserv- 
ing its  name  ;  on  the  South  by  the  jagged  double  peak  of 
Mt.  Moss,  or  Mt.  Hayden  as  it  is  locally  called,  and  on  the 
East  by  Snowstorm  Peak,  which  justified  its  cognomen  dur- 
ing our  stay  in  its  neighborhood  by  covering  itself  with  a 
fresh  coat  of  white  in  the  middle  of  July.  None  of  these

outlying  peaks  rival  the  central  mass  of  Mt.  Hesperus, 
but  all  reach  nearly  or  quite  13,000  feet,  and  their  sheltered 
gulches  hold  £.buadaut  snow  far  into  the  summer  to  feed 
the  mountain,  brocks,  and  furnish  moisture  for  the  luxuri- 
&i it  plpirie  vegetation  that  springs  up  like  magic  as  the 
snow  line  retreats.  From  the  basins  between  these  peaks 
arise  many  streams.  The  La  Plata  River  rises  to  the  east- 
ward of  Hesperus  and  flows  nearly  due  South ;  East, 
Middle,  and  West  Mancos  creeks  flow  from  its  western 
flanks,  all  uniting  above  the  town  of  the  same  name  to 
form  the  Mancos  River,  which  flows  in  a  southwesterly 
direction.  Bear  Creek  rising  North  of  Hesperus,  between 
that  peak  and  Shark's  Tooth,  flows  to  the  northwestward, 
while  the  drainage  from  the  eastern  side  of  Shark's  Tooth 
and  Snowstorm  Peak  and  is  tributary  to  the  Las  Animas. 

Two  of  our  party  reached  the  little  town  of  Mancos  on 
the  Rio  Grande  Southern  railway  on  Tuesday,  June  21, 
1898,  and  went  into  camp  near  the  river  to  await  the  com- 
ing of  the  third  member  who  had  been  detained  at  his 
home  in  Mississippi  by  a  suddenly-imposed  yellow  fever 
quarantine. 

The  valley  at  Mancos  is  from  one  to  two  miles  wide.  For- 
merly a  sage  plain,  it  is  now,  thanks  to  irrigation,  mostly 
covered  with  green  wheat  and  alfalfa  fields.  Owing  to  its 
elevation.  7,000  feet,  corn  and  the  more  tender  vegetables 
can  not  be  grown  on  the  Mancos.  To  the  North  and  East 
the  valley  is  bounded  by  the  foot  hills  and  lower  ridges  of 
the  La  Plata  Range,  the  snow-streaked  top  of  Hesperus 
being  plainly  visible.  The  hills  bounding  the  valley  to 
the  South  are  strikingly  different  from  these  in  conforma- 
tion, being  flat-topped  with  precipitous  sides,  evidently 
belonging  to  the  great  mesa  formation  of  the  Southwest. 
The  steep  northern  slopes  of  these  mesas  facing  the  valley

are  covered  by  a  dense  growth  of  chaparral,  giving  them  in 
the  distance  a  deep  blue  or  almost  black  effect.  This  cha- 
parral consists  largely  of  scrub  oak  Quercus  undulata  inter- 
spersed or  sometimes  almost  replaced  by  clumps  of  Ame- 
lanchier,  Peraphyllum,  Rhus,  Fendlera,  and  Cercocar- 
pus.  The  summits  of  the  lower  foot  hills  on  either  side  of 
the  valley  support  a  scattered  growth  of  nut  pine  and  red 
cedar, Pinus  edulis  and  Juniperus  monosperma.  Looking  west- 
ward the  eye  wanders  over  great  stretches  of  undulating 
sage  plains  and  pinon-covered  ridges  to  the  Blue  Mountains 
of  Utah  a  hundred  miles  away.  Southwestward  the  view 
is  limited  by  the  less  elevated  Ute  Mountain  Range,  lying 
distant  some  thirty  miles. 

The  five  days  of  a  necessary  detention  at  Mancos  were 
devoted  to  the  flora  of  the  valley;  and  these  proved  quite 
as  instructive  as  any  equal  portion  of  time  spent  at  higher 
altitudes.  Three  well-defined  floral  belts  were  reached  from 
this  riverside  camp.  First,  the  flood  plain  of  the  Mancos,  a 
narrow  bottom,  varying  from  a  few  yards  to  a  quarter  of  a 
mile  in  width.  Some  parts  of  it  are  grassy  and  meadow- 
like  ;  others  occupied  by  swampy  thicket.  The  largest  trees 
are  those  of  the  narrow-leaved  poplar,  Populus  angustifolia ; 
and  this  was  the  only  member  of  its  genus  seen  here, 
except  the  aspen.  The  buffalo  berry,  Lepargyrea  argentea, 
conspicuous  by  its  silver-gray  foliage,  is  abundant,  forming 
large  clumps,  and  reaching  the  height  of  fifteen  and  even 
twenty  feet.  The  thickets  are  composed  of  various  willows, 
interspersed  with  some  choke-cherry  trees,  Cerasus  demissa, 
and  dogwoods,  Cornus  stolonifera  ;  these  supplemented  by 
dense  masses  of  Distegia  involucrata  reminding  one  of  the 
hedges  of  so-called  "buckbrush,"  Cephalanthus,  bordering 
the  banks  of  swampy  lakes  in  Mississippi  River  bottoms. 

At  this  elevation  the  Distegia  (the  Lonicera  involucrata  of 


4  PLANT.E    BAKERIAN.E. 

some  authors)  attains  the  height  of  eight  or  ten  feet;  but  up 
near  the  timber-line  it  is  a  dwarf  of  sometimes  not  more 
than  one  or  two  feet.  The  more  conspicuous  herbaceous 
plants  of  these  thickets  are  Mertensia  ciliata,  Geranium  Rich- 
ardsonii,  a  new  species  of  buttercup,  Ranunculus  Earlei 
(Greene),  and  Polemonium  filicinum,  a  species  originally  from 
southern  New  Mexico,  and  which  here  it  may  be  assumed, 
reaches  its  northern  limit  of  distribution.  Among  such  as 
these  were  also  gathered  a  few  herbaceous  plants,  notably 
Carex  aurea  and  Collomia  lanceolata,  and  several  more,  which 
are  more  properly  subalpine  and  alpine.  And  as  we  after- 
wards grew  familiar  with  the  whole  region,  including  the 
higher  elevations  about  the  headwaters  of  this  stream  less 
than  twenty  miles  away,  the  wonder  constantly  grew,  not 
that  only  a  few  alpine  or  subalpine  plants  should  occur  in 
the.  valley  below,  but  that  so  few  of  these  species  had  been 
able  to  adapt  themselves  to  the  condition  of  the  lower  levels 
even  where  the  cool  thickets  furnished  such  excellent  shade 
with  abundant  moisture,  and  the  rapidly  flowing  stream 
offered  such  abundant  facilities  for  the  downward  distribution 
of  seeds.  As  a  rule  the  Mancos  specimens  of  species  having 
a  considerable  altitudinal  distribution'  were  taller  and  more 
slender  than  those  subsequently  taken  in  mountain  mea- 
dows ;  which  variation  seems  attributable  partly,  at  least,  to 
their  having  grown  in  the  shade.  But  in  other  cases,  such 
as  the  Collomia  and  Carex  aurea,  the  low  elevation  seemed 
to  have  had  the  opposite  effect  of  dwarfing  the  plants ;  speci- 
mens from  about  Mancos  being  much  smaller  than  those 
taken  at  elevations  greater  by  a  thousand  feet. 

Separated  from  the  flood-plain  by  a  steep  bank  five  to  fif- 
teen or  even  twemty  feet  high,  and  constituting  a  more 
elevated  secondary  bottom,  the  sage  plain  stretches  away 
for  a  mile  or  more  on  either  side  of  the  valley  to  the  foot-

hills.  This  tract,  as  I  have  said,  has  in  part  been  reclaimed 
and  brought  under  cultivation.  Originally  it  was  covered 
with  low-growing  gray-green  chenopodiaceous  and  composite 
shrubs,  such  as  constitute  what  is  commonly  called  sage 
brush.  Those  portions  not  under  cultivation  exhibit  these 
growths,  intermixed  with  clumps  of  bushy  Amelanchier  and 
Peraphyllum  representing  the  family  of  the  Pomacese;  and 
it  also  supports  a  peculiar  and  most  interesting  herbaceous 
flora,  made  up  of  Lupinus  argenteus  and  other  lupines, 
numerous  species  of  Astragalus  and  other  papilionacese, 
several  Pentstemons  and  Castilleias,  Allium  acuminatum 
and  Calochortus  Gunnisonii  representing  the  lily  family. 

The  pinon  belt  occupies  the  low  foothills  from  1 00  to  400 
or  500  feet  above  the  valley.  Here  Pinus  edulis  and  Juni- 
perus  monosperma  combine  in  not  unequal  proportions  to 
form  a  low  scraggy  woodland  growth.  Neither  species  often 
exceeds  twenty  feet  in  height,  and  each  is  frequently 
adorned  by  its  own  species  of  parasitic  Razoumoffskia  and 
Phoradendron.  Herbage  is  scanty  in  this  belt,  and  the  her- 
baceous species  quite  characteristic,  like  Lescuriella  Palmeri, 
Pentstemon  linarioides,  Astragalus  scopulorum  and  Picradenia 
Richardsonii. 

Our  belated  Mississippian,  Professor  Tracy,  arrived  in  the 
morning  of  June  26  and  we  started  at  once  for  the  western 
flank  of  Mt.  Hesperus,  our  wagon  piled  high  with  boxes  of 
paper,  presses,  bundles  of  driers  and  camp  equipage.  Our 
plan  was  to  make  a  somewhat  permanent  camp  as  near 
timber  line  as  we  could  go  with  a  wagon,  and  then  to  take 
time  to  thoroughly  explore  the  country  both  above  and 
below.  Our  road  started  due  north  from  Mancos  but  soon 
bore  northeast  and  followed  up  a  rather  narrow  ridge  or 
divide  between  the  deep  rocky  canon  of  the  West  Mancos 
on  the  right,  and  Chicken  Creek,  a  smaller  tributary  of  the 


6  PLANTS    BAKERIAN^E. 

Mancos,  on  the  left.  About  four  miles  from  town,  and  at 
an  elevation  of  some  7,500  feet,  we  left  the  piiions  and  the 
chaparral-covered  hillsides  through  which  we  had  been 
traveling,  and  came  suddenly  into  magnificent  open  pine 
woods.  Our  driver  told  us  that  the  lumbermen  distin- 
guished two  kinds  of  pine,  but  all  seemed  to  be  Pinus  sco- 
pulorum  the  difference  in  the  timber  being  probably  due  to 
differences  in  the  age  and  condition  of  the  trees.  Many  of 
the  pines  are  of  large  size  and  the  ground  between  them, 
while  mostly  clear  of  brushwood,  yields  a  sufficient  growth 
of  grass  and  herbage  to  give  it  an  attractive  park-like  effect. 
Though  the  collecting  in  this  lower  part  of  the  pine  belt 
was  not  specially  interesting,  it  furnished  a  few  charac- 
teristic plants,  such  as  Lotus  Wrightii  and  Lithospermum 
multiflorum. 

Advancing  toward  higher  ground,  the  winding  road 
brought  us  to  an  elevation  of  about  9,000  feet,  where  the 
pines  give  place  to  aspen  thickets.  At  this  point  we  ob- 
tained our  first  impression  of  the  riches  of  vegetation 
belonging  to  the  higher  mountains;  for  the  aspen  thickets 
of  limited  extent  were  found  to  alternate  with  considerable 
stretches  of  native  meadow  brilliant  with  a  great  diversity  of 
flowers  blooming  among  the  abundant  grasses.  Fields  of 
the  large  sunflower-like  Wyethia  Arizonica,  clumps  of  purple 
lupine  bordering  these,  red  Castilleias  and  white  Polygonum 
bistbrtoides,  Potentillas  of  several  sorts  along  with  other 
things  as  showy  combined  to  form  a  beautiful  and  most 
inviting  botanical  landscape. 

Still  continuing  the  gradual  ascent,  spruces  (Picea  Engel- 
mannii)  began  to  intersperse  themselves  in  groups  among 
the  aspen  clumps,  becoming  gradually  more  and  more  pre- 
ponderant, until  finally  the  aspens  cease  altogether  at  11.000 
eet,  where  the  spruces  thenceforward  hold  undisputed  sway

up  to  the  timber-line  which,  in  this  latitude,  is  at  about 
11,500  feet. 

Having  made  a  late  start,  on  this  first  day  of  the  ascent, 
we  covered  only  about  fifteen  miles,  camping  for  the  night 
near  the  head  of  Chicken  Creek.  A  little  beyond  this  point 
our  road  descended  abruptly  into  the  West  Mancos  Canon, 
thence  following  that  stream  up  to  Jackson's  stamp  mill, 
at  the  very  base  of  Mt.  Hesperus.  The  difficulty  of  getting 
our  heavy  outfit  back  out  of  this  deep  canon  seemed  so 
great  that  we  decided  to  keep  on  up  the  ridge,  following 
some  old  cattle  and  pack  trails  as  far  as  it  should  prove 
practicable  to  take  the  wagon.  We  succeeded  in  getting 
three  or  four  miles  further,  and  made  our  second  camp  on 
the  headwaters  of  a  little  tributary  of  the  West  Mancos 
locally  known  as  Bob  Creek.  We  had  reached  an  elevation 
of  10,500  feet  and  were  about  two  and  a  half  miles  due  west 
of  the  main  peak  of  Mt.  Hesperus,  but  with  the  deep  and 
rugged  valley  of  Slide  Rock  Creek  lying  between.  The 
laborious  climb  out  of  this  valley  with  a  heavy  load  of 
plants,  after  a  day's  collecting  on  Hesperus  convinced  us 
that  we  had  made  a  mistake  in  not  taking  the  lower  road 
and  so  pitching  our  camp  in  the  canon,  when  the  home- 
ward trip  would  always  have  been  down  hill. 

The  region  above  timber  was  reached  in  three  different 
places  from  this  Bob  Creek  camp,  on  the  southwest  face  of 
the  ridge  between  West  Mancos  and  Slide  Rock  Creeks, 
which  constitutes  the  westernmost  spur  of  Mt.  Hesperus,  on 
the  north  face  of  the  same  ridge  farther  east  near  the  head 
of  Slide  Rock  Creek,  and  on  the  Bear  Creek  divide  north- 
east of  camp.  In  all  these  places  the  ground  was  rather 
dry  and  exposed.  Many  interesting  plants  were  taken,  but 
the  full  glory  of  the  alpine  vegetation  was  not  seen  till  we 


8  PLANTS    BAKERIASLE. 

reached  the  moister  basins  at  the  head  of  the  La  Plata 
River  on  the  eastern  side  of  the  range. 

One  of  the  most  interesting  features  of  this  western  flank 
of  the  range  was  the  great  reaches  of  verdant  mountain 
meadow  stretching  away  in  every  direction  between  the 
scattered  clumps  of  spruces  and  aspens.  The  grass,  con- 
sisting largely  of  Poas  and  Festucas,  was  exceedingly 
luxuriant  and  was  everywhere  sprinkled  or  crowded  by 
showy  species  of  Mertensia,  Polemonium,  Valerianella, 
Frasera,  Veratrum,  Aconitum,  Delphinium  and  numberless 
other  smaller  flowering  plants. 

The  morning  of  July  6  found  us  breaking  camp  and 
starting  on  the  return  trip  to  Mancos.  The  season  was  now 
at  its  height,  and  it  was  marvelous  to  see  how  rapidly  vege- 
tation was  developing  at  these  high  altitudes.  Had  time 
permitted  we  should  gladly  have  lingered  longer  at  this 
camp,  for  each  day  brought  new  species  into  bloom,  and  it 
seemed  to  our  regretful  eyes  that  we  were  leaving  more  still 
undeveloped  species  behind  us  than  we  had  found  in  con- 
dition to  collect.  The  trip  back  to  Mancos  occupied  two 
days,  as  much  time  was  consumed  in  collecting  on  the  way 
the  things  that  had  opened  during  our  brief  absence.  A 
further  stop  of  two  days  in  Mancos  enabled  us  to  pack  and 
ship  the  dried  plants  that  had  accumulated,  and  to  take  a 
short  side  trip  over  the  sage  plains  to  the  south  west  ward  along 
the  road  toward  Cortez,  in  the  direction  of  the  Ute  Moun- 
tain. This  day's  collecting  proved  to  be  the  richest  in  the 
number  of  specimens  taken  and  in  the  number  of  new 
species  of  flowering  plants  discovered  of  any  on  the  entire 
trip,  thus  showing  that  in  planning  future  work  in  this 
region  the  lower  levels  should  receive  careful  attention. 

The  afternoon  of  July  9  found  us  again  under  way  for 
a  trip  up  the  La  Plata  Valley  on  the  east  side  of  Mt. 


NARRATIVE.  9 

Hesperus.  Our  route  lay  over  some  low  divides  through  a 
rather  uninteresting  country,  part  of  the  time  in  oak 
chaparral,  and  at  times  getting  up  into  the  open  pine  belt. 
During  the  afternoon  of  July  10  we  passed  Dix  P.  0. 
and  reached  the  old  mining  camp  of  Parrott  City  at  the 
foot  of  the  mountains,  just  at  the  entrance  to  the  canon 
of  the  La  Plata  River.  Continuing  a  few  miles  further,  we 
made  camp  in  the  bottom  of  the  canon  about  two  miles 
south  of  La  Plata  City.  This  was  one  of  the  richest  spots 
visited.  The  bottom  of  the  valley  is  only  a  few  hundred 
yards  wide,  and  it  is  walled  in  on  either  side  by  the  pre- 
cipitous slopes  of  the  mountains.  It  is  very  moist,  and  is 
filled  with  a  luxuriant  tangle  of  vegetation.  Rubus  Nutkanus 
here  grows  to  perfection,  and  the  ground  is  fairly  carpeted 
with  the  showy  Eyigeron  coulteri  and  Penstemon  glaucus 
stenosepalus.  The  gravel  banks  in  the  stream  also  furnished 
conspicuous  and  abundant  species,  including  Epilobium 
latifolium  and  Senecio  atratus.  The  elevation  here  was  about 
9,000  feet. 

On  July  12  we  again  moved  camp  going  toward  the  head 
of  the  valley.  Above  the  town  of  La  Plata  the  canon  grows 
much  narrower  and  the  grade  is  much  steeper.  The  road  is 
soon  forced  to  leave  the  stream  and  is  cut  into  the  hillside. 
For  a  considerable  distance  no  suitable  place  for  a  camp 
could  be  found,  but  finally  just  below  the  mouth  of  Basin 
Creek,  at  about  10,000  feet  elevation,  a  projecting  ledge  of 
rock  gave  us  just  room  to  put  up  the  tent  and  get  the  wagon 
out  of  the  road.  Stakes  being  out  of  the  question  tent  ropes 
were  made  fast  to  boulders,  and  our  quarters,  though  re- 
stricted, proved  sufficiently  comfortable.  Wagon  roads  have 
been  constructed  several  miles  farther  to  reach  various 
stamp  mills,  but  they  were  so  rough  and  steep  that  we 
did  not  attempt  to  take  our  heavy  outfit,  beyond  this 


10  PLANTS    BAKERIAN.E. 

point  but  made  daily  trips  above  timber  line  in  various 
directions. 

The  basins  of  the  small  streams  far  above  timber  line 
were  here  all  veritable  alpine  gardens  well  stocked  with 
Mertensias,  Polemoniums,  Trifoliums,  Erigerons,  Castilleias 
and  many  other  showy  alpine  genera.  Even  the  most 
rugged  slopes  exhibited  a  great  diversity  of  species ;  for 
every  nook  and  crevice  among  the  rocks  where  any  soil  had 
found  a  lodgment  was  filled  with  plants.  On  the  very 
summit  of  Mt.  Hayden  at  13,000  feet  we  gathered  excel- 
lent specimens  of  Trifolium  nanum,  Chionophila  Jamcsii, 
Ligusticum  Eastwoodix  and  Pentstemon  Harbourii. 

It  is  to  be  noted  that  about  three-fourths  of  the  plants 
collected  here  were  of  species  not  represented  at  any  of  the 
lower  altitudes. 

It  was  with  much  regret  that  on  July  16  we  took  leave 
of  this  interesting  locality  and  made  our  way  to  Durango. 
Each  little  sheltered  slope  and  basin  that  we  visited  fur- 
nished some  plant  not  seen  elsewhere,  and,  had  time  per- 
mitted a  thorough  exploration  of  the  region  our  list  of 
species  would  have  received  many  additions.  Furthermore, 
the  flowering  season  had  not  yet  reached  its  fullness.  Very 
many  species  were  not  yet  beginning  to  bloom,  and  it  was 
manifest  that  a  month's  sojourn  would  have  enabled  us  to 
nearly  double  our  collections. 

This  Alpine  research  was  disappointing  in  respect  to  only 
two  groups  of  plants.  Of  ferns  we  took  but  two  species, 
Cystopteris  fragilis  and  Cryptogramme  acrostichoides ;  and  the 
number  of  lichens  was  much  smaller  than  had  been  antici- 
pated. The  bare  rocks  supported  a  fair  number  of  crusta- 
ceous  species,  which,  owing  to  the  early  loss  of  our  chisel, 
we  were  unable  to  collect;  and  terrestrial  and  arboreal 
species  were  very  scarce. 


NARRATIVE.  11 

Durango  is  a  thriving  town  located  in  the  valley  of  the 
Las  Animas  river  at  an  elevation  of  6,500  feet.  South  of  the 
town  the  hills  rise  1,000  or  1,500  feet  higher.  They  are 
mostly  composed  of  beds  of  shale  with  a  few  coal-bearing 
strata  and  so  give  but  few  plants  of  interest  during  the  hot 
midsummer  months,  even  along  the  narrow  ravines  and 
arroyas.  The  Grindelias,  Mentzelias  and  Eriogonums 
found  within  the  city  limits  proved  fully  as  interesting  as 
the  plants  of  these  nearby  hills.  In  some  places  they  sup- 
port a  considerable  growth  of  Juniperus  monosperma  with 
scattered  trees  of  pinon.  Near  the  eastern  edge  of  the 
town  one  small  hill  was  noticed  that  had  been  covered  by  a 
rather  dense  growth  of  this  juniper,  but  now  only  a  few  of 
the  trees  were  living,  the  others  having  apparently  been 
killed  by  Gymnosporangium  speciosum  Peck,  which  had  left 
the  swollen  and  distorted  trunks  marked  with  its  peculiar 
plicate  tumors. 

North  of  town  toward  Trimble  Springs  the  Animas  valley 
is  somewhat  broader,  though  bounded  on  each  side  by  pre- 
cipitous mountain  walls  which  rise  from  2,000  to  2,500  feet 
above  the  stream.  Every  acre  of  irrigable  land  is  in  a  high 
state  of  cultivation,  hay  or  green  fields  and  orchards  filling 
all  the  valley  from  Durango  to  where  the  Hermosa  River 
joins  the  Animas.  Here  we  noted  similar  willows  to  those 
found  at  Mancos  and  at  the  base  of  the  cliffs  were  box  elders 
and  Eibes  cereum. 

Through  the  kindness  of  Col.  Thomas  Hamor,  of  Durango, 
we  were  enabled  to  make  a  somewhat  hasty  trip  to  Colum- 
bine, twenty-five  miles  north  of  Durango,  on  the  old  Silverton 
trail,  and  only  a  few  miles  to  the  eastward  of  our  Upper 
La  Plata  camp.  The  place  is  near  the  head  of  the  valley, 
and  Hamor's  Lake,  a  picturesquely  beautiful  sheet  of  water, 
is  one  of  the  sources  of  the  Las  Animas  river.  The  lake 


12  PLANTS    BAKERIAN.E. 

seems  to  have  been  formed  by  the  sudden  closing  in  of  the 
canon  wall  so  that  though  not  large  it  is  of  great  depth.  It 
is  as  clear  as  crystal  and  even  after  our  visit  it  still  contains 
some  magnificent  trout.  The  elevation  here  is  about  9,000 
feet  and  the  hills  and  wet  meadows  near  the  lake  yielded  a 
greater  number  of  species  than  any  other  equal  area  that 
we  visited.  In  the  water  of  the  lake  itself  was  an  abun- 
dance of  Chara  Hippuris  and  Potamogeton  while  on  its 
borders  were  Thalidrum  alpinum,  Gentiana  heterosepala,Swertia 
scopulina,  Agastache  wrticsefolia,  Lilium  montanum  and  many 
other  species  not  taken  elsewhere. 

Mr.  Tracy,  who  was  the  last  to  arrive,  remained  in  the 
neighborhood  of  Durango  until  July  28.  Messrs.  Earle 
and  Baker  departed  on  the  18th  and  19th  respectively, 
making  about  an  even  month  in  the  field  for  each  of  the 
three  members  of  the  expedition. 

Perhaps  the  most  striking  impression  gained  by  the  trip, 
aside  from  that  produced  by  the  abundance  and  beauty  of 
the  high  alpine  flora,  is  that  of  the  distinctness  with  which 
the  different  altitudinal  floral  zones  are  marked  out  and 
limited.  It  is  true  a  few  species  were  found  all  the  way 
from  the  Mancos  River  bottoms  at  7,000  feet  to  timber  line 
at  11,500  feet,  but  these  instances  are  rare.  In  the  great 
majority  of  cases  each  species  observed  had  an  altitudinal 
range  of  not  to  exceed  1,000  feet,  even  with  similar  con- 
ditions of  soil  and  moisture.  In  a  general  way  these  life 
zones  seemed  to  be  the  same  here  as  in  the  not  far  distant 
San  Francisco  Mountains  of  Arizona,  where  they  have  been 
so  carefully  studied  by  Dr.  Merriam,  of  the  U.  S.  Biological 
Survey.  We  could  easily  distinguish  the  pinon-cedar  belt, 
the  pine  belt,  the  aspen-spruce  belt  and  the  timber  line  belt 
as  designated  by  him,  and  we  found  this  division  a  very 
useful  one  in  the  prosecution  of  our  work. 


NARRATIVE.  13 

While  we  endeavored  to  make  our  work  as  thorough  as 
possible  for  the  very  limited  region  actually  explored,  we 
realize  fully  that  it  is  only  a  beginning.  The  number  of 
plants  collected  serves  to  illustrate  the  great  floral  richness 
of  the  region,  and  our  experience  suggests  that  for  future 
work  the  higher  mountains  should  be  visited  during  the 
period  from  July  15  to  September  1,  when  an  almost 
entirely  new  set  of  plants  would  be  in  bloom;  and  that 
work  in  the  lower  levels,  especially  in  the  canon  and  mesa 
region  south  and  west  of  Mancos  is  greatly  needed  earlier 
in  the  season,  say  from  May  1  to  June  15.  It  is  hoped 
that  at  least  some  of  our  party  may  be  able  to  continue  the 
work  another  season.

FUNGI.

Among  the  more  striking  features  of  the  fungus  flora  of 
the  region  which  the  collection  represents  may  be  men- 
tioned the  great  abundance  of  the  Uredinales  and  Sphseriales. 
The  Erysibacese  would  have  been  abundant  later  in  the 
season,  though  only  two  species  were  found  in  condition  to 
collect.  Perisporacese  were  entirely  lacking,  as  were  also  the 
Hysteriales,  though  the  latter  were  persistently  sought  for 
everywhere.  The  Pezizales  are  represented  by  only  two 
species.  The  Helvellales  do  not  appear  in  the  list,  but  fine 
specimens  of  Morchella  and  Gyromitra  were  observed  in  the 
high  spruce  woods.  The  Agaricacese  are  very  scantily  rep- 
resented in  the  list,  but  they  were  really  quite  abundant  in 
moist  locations  at  the  higher  altitudes.  Lack  of  time  and 
of  facilities  for  properly  drying  the  specimens  prevented 
collecting  them.  Among  the  Sphssriales  which  constitute 
nearly  a  third  of  all  the  species  collected,  and  of  which  con- 
siderably over  one-half  proved  to  be  undescribed,  the  almost 
entire  absence  of  such  common  eastern  genera  as  Hypoxylon 
and  Valsa  is  to  be  noted,  as  well  as  the  great  abundance  of 
Lophiostomatdcese,  a  family  rarely  found  by  eastern  col- 
lectors. The  Dothideales  and  Hypocreales  are  each  repre- 
sented by  a  single  species  only. 

It  is  interesting  to  note  that  of  the  entire  collection  only 
the  following  five  species  were  taken  above  timber  line: 
Schizonella  melogramma,  Puccinia  acrophila,  P.  Claytoniatum, 
P.  Pimpinelldz  and  Patinella  Crandallii.  .  The  smallness  of  this 
list  is  to  be  accounted  for  in  great  part  by  the  fact  that  our

time  above  timber  line  was  always  limited  and  that  the 
beauty  and  abundance  of  the  flowering  plants  claimed  our 
attention,  to  the  neglect  of  the  Fungi. 

In  the  following  list  the  sequence  of  families  is  that  of 
Engler  &  Prantl.  In  the  few  cases  in  which  the  generic 
name  used  by  us  is  another  than  that  employed  by  Saccardo 
in  the  Sylloge  Fungorum,  the  latter  is  added  in  parenthesis.

The  differences  he  so  clearly  pointed  out  between  this  and 
the  European  P.  Arenarise  indicate  it  to  be  a  distinct  species,

seen  on  the  upper  La  Plata  at  10,000  feet.  Some  three 
dozen  specimens  of  this  magnificent  Boletus  were  taken,  but 
owing  to  constant  showers,  and  lack  of  drying  facilities,  all 
but  one  were  lost.  Two  other  species  of  the  genus  were 
seen,  but  it  was  not  possible  to  preserve  them.

June  29,  n.  232. 

This  has  not  before  been  reported  from  America.  The 
asci  soon  vanish,  and  at  full  maturity  the  ascospores  are 
fuliginous.  In  our  specimens  the  perithecia  often  reach 
5mm.  In  other  respects  it  closely  agrees  with  the  descrip- 
tion given  by  Hartig.  It  was  also  observed  on  Mt.  Hes- 
perus near  timber  line,  but  was  not  seen  below  H',000  feet. 
This  was  previously  collected  by  C.  F.  Baker  on  spruce  in 
northern  Colorado,  July  13,  1896,  at  Cameron  Pass,  10,000 
feet,  and  distributed  by  him  under  the  name  of  Lasiosphdsria 
Coulteri,  Peck.  It  closely  resembles  that  pine-inhabiting 
species  externally,  but  the  spores  are  entirely  different.

On  dead  twigs  of  SymphoricarpuSj  Bob  Creek,  10,500  feet, 
June  27,  n.  173,  with  Rosellinia  parasitica  and  Strickeria  Sym- 
phoricarpi.  The  true  generic  position  of  this  species  is 
somewhat  doubtful.  Its  scanty  imperfect  stroma  suggests 
that  it  should  be  placed  in  the  Cucurbitariacege  rather  than 
in  Mellogramma,  but  the  vestiture  of  the  perithecia  would 
exclude  it  from  Gibberidia,  as  that  genus  is  now  denned. 
Since  perithecial  hairs  are  present  in  the  nearly  related 
Gibbera,  from  which  our  species  is  excluded  by  the  spore 
characters,  we  prefer  to  widen  the  definition  of  Gibberidia 
rather  than  to  propose  a  new  genus  based  only  on  the  pres- 
ence of  perithecial  hairs.

INTRODUCTORY. 


Mr.  Baker's  ample  and  most  interesting  collection  of  the 
year  1899  was  made,  as  his  own  brief  and  pointed  Itinerary 
will  indicate,  along  the  borders  of  southwestern  Colorado 
and  adjacent  New  Mexico.  The  field  was  one  wisely 
selected,  as  the  large  proportion  of  new  plants  obtained  suf- 
ficiently declares;  while  the  great  extent  of  the  collection 
shows  how  vast  an  amount  of  travelling  and  of  other  physi- 
cal labor  the  zeal  and  industry  of  one  strong  and  vigorous 
young  man  can  accomplish  in  a  single  season,  and  as  it 
were  single  handed. 

Our  report  upon  this  rich  and  beautiful  collection  will 
constitute  Volume  II  of  the  PLANTS  BAKERIAN^E.  The 
material  has,  at  this  date,  for  the  most  part  been  quite  care- 
fully studied,  and  it  is  hoped  that  at  intervals  not  widely 
separated  the  succeeding  instalments  of  the  volume  may 
reach  the  hands  of  the  subscribers  to  the  sets. 

Inasmuch  as  this  second  volume  will  inevitably  catalogue 
many  species  that  were  reported  in  the  first  volume,  the 
names  of  such  as  are,  as  it  were,  duplicated  in  the  collection 
of  1899,  will  be  printed  in  italics  here,  only  such  being  ex- 
cepted  as  were  published  as  new  in  the  first  volume.  The 
names  of  these  will  be  given  in  the  usual  small  capital  type.

ITINERARY. 

By  CARI,  F.  BAKER. 

The  first  camp  of  1899  was  established  early  in  March  at 
Hermosa,  Colorado,  at  about  6,700  feet  altitude,  in  the  upper 
Animas  Valley  and  on  the  west  slope  of  the  Needle  Moun- 
tains. At  this  time,  alder  and  the  first  willows  were  in 
bloom,  and  a  few  days  later  the  first  Cymopterus  appeared. 
A  few  unopened  flower  buds  of  Townsendia  sericea  were  also 
seen.  During  this  month  special  attention  was  given  to 
mosses,  lichens  and  fungi,  with  good  results.  By  April  1 
Pulsatilla  began  to  bloom. 

On  April  10  the  second  camp  was  made  on  the  banks 
of  the  San  Juan  River,  just  below  the  town  of  Aztec,  New 
Mexico,  at  an  altitude  of  about  5,500  feet.  This  region  is 
characterized  by  sand  hills  and  gravelly  mesas,  sparingly 
covered  with  pinon  pine  and  cedars,  the  whole  very,  very 
dry.  The  hills  along  the  extreme  southern  border  of  Colo- 
rado do  not  differ  essentially  in  many  places  from  the  Aztec 
hills,  and  the  distance  is  not  great.  Undoubtedly  most  of 
the  plants  found  at  Aztec  will  also  be  found  in  Colorado. 
Many  things  were  coming  into  bloom  when  camp  was  made 
at  Aztec.  During  the  month  it  was  found  that  a  very  re- 
markable and  evanescent  flora  existed  among  these  hills. 
This  flora  appears  during  the  very  earliest  warm  days  of 
spring.  The  plants  arise  from  perennial  bases,  flower  and 
fruit  very  rapidly,  and  have  passed  before  hardly  any  of  the 
plants  usually  considered  so  characteristic  of  the  region  are 
in  their  prime.  Of  most  things,  specimens  were  few  and 
scattering.  Miles  and  miles  of  the  interminable  pinon  hills 
were  tramped  over  to  secure  enough  for  issuance.  On  many 
of  the  days,  the  cold  northwest  winds  were  extremely  bitter. 


IV  PLANTS    BAKERIAN^E. 

The  statement  that  all  plants  in  the  '99  sets  from  this 
locality  were  taken  during  April  or  the  first  few  days  in 
May  has  seemed  surprising,  even  to  those  best  acquainted 
with  collecting  in  the  southwest.  Summer  and  fail  collect- 
ing in  this  locality  would  unquestionably  give  very  inter- 
esting results. 

During  the  early  days  of  May  camp  was  moved  far  up 
the  valley  of  the  Rio  de  los  Pinos  to  the  lower  end  of  Gra- 
ham's Park  at  an  altitude  of  7,800  feet.  Here  the  results 
of  a  cold,  dry  spring  were  very  evident,  and  collecting  was 
poor. 

On  the  15th  of  the  month  camp  was  moved  down  the 
valley  to  Los  Pinos  P.  0.  (also  known  as  Bayfield)  on 
the  same  river,  at  about  7,000  feet  altitude.  This  place  is 
just  north  of  the  Ute  Reservation  line,  and  on  the  zonal 
division  between  Pinus  edulis  (pinon)  and  Pinus  ponderosa. 
Here  were  still  further  signs  of  drought.  Collecting  was 
n  ecessarily  largely  confined  to  the  river  bottoms  and  ground 
moistened  by  seepage  from  irrigating  ditches. 

On  June  1  camp  was  moved  to  Arboles,  in  the  river  bot- 
tom at  the  junction  of  the  Rio  San  Juan  and  Rio  Piedra, 
only  a  few  miles  above  the  New  Mexican  border.  Collections 
were  made  here  and  also  at  Rosa,  New  Mexico.  Numerous 
large  flocks  of  sheep  were  rapidly  devastating  the  narrow 
bottoms.  The  destruction  could  scarcely  have  been  more 
complete  had  the  work  been  done  by  fire.  A  number  of 
very  interesting  plants  were  found  among  the  very  dry 
sandy  hills  and  along  the  stony  mesa  banks, — among  them 
a  new  Coleosanthus,  two  new  Astragali,  and  a  new  Carduus. 
As  at  Aztec,  these  hills  are  covered  sparsely  with  pinon, 
pine  and  cedar,  though  otherwise  the  two  localities  are  very 
distinct. 

The   next  move  made  was  up  the  Rio  Piedra  to  Piedra 


ITINERARY.  V 

P.  0.,  at  about  7,000  feet  altitude  and  well  within  the 
Pinus  ponder osa  zone.  As  will  be  seen  from  the  Colorado 
Forestry  Commission  map,  this  zone  curves  strongly  to  the 
southeast,  east  of  Durango,  following  the  trend  of  the  San 
Juan  range.  The  road  up  the  Piedra  valley  is  new  and 
extremely  rough.  An  entire  lack  of  bridges  necessitated 
fording  the  river  many  times.  Frequently  the  wagon  wheels 
became  wedged  among  the  boulders  of  the  river  bed,  com- 
pelling the  carrying  out  of  the  entire  load  through  the  ice 
cold  waters,  by  hand.  Habenaria  hyperborea  was  unex- 
pectedly found  about  a  cool  spring  in  a  dark  shady  gulch 
near  Piedra  and  a  new  Cypripedium  at  the  same  place. 

During  the  last  of  July  a  move  was  made  to  Pagosa 
Springs  (at  about  7,100  feet)  over  a  good  road  passing 
through  magnificent  forests  of  Pinus  ponderosa.  The  end 
of  these  forests  is  in  sight,  their  destruction  being  actively 
under  way  now.  The  desolation  caused  by  the  lumberman 
and  the  fires  which  follow  in  his  wake,  is  an  evidence  of  an 
appalling  lack  of  foresight,  not  possible  in  the  more  scienti- 
fically enlightened  countries.  In  a  favorable  year  Pagosa 
Springs  would  unquestionably  be  the  most  promising  head- 
quarters in  southwestern  Colorado  for  mountain  botanizing. 
It  is  the  center  of  a  wonderful  region,  man}r  distinct  topo- 
graphical areas  being  readily  accessible.  The  unusually  fine 
hot  springs  at  this  place  attract  many  tourists  through  the 
season.  Above  this  point  are  some  of  the  finest  natural 
meadows  in  the  State.  Under  ordinary  circumstances,  at 
this  season  of  the  year  there  is  still  much  snow  on  the  sur- 
rounding mountains.  But  in  1899  none  could  be  seen  and 
the  terrible  drought  was  at  its  height.  Sheep  and  cattle 
were  hurried  up  from  the  lower  levels,  though  many  died 
of  hunger  and  thirst.  The  most  striking  plant  at  this  point 
was  Rhamnus  Smithii. 


VI  PLANTS    BAKERIAN^E. 

About  August  1  another  move  was  made  over  a  road 
just  built  for  mining  purposes  to  Camp  Loraine,  in  a 
narrow  basin  between  Pagosa  Peak  and  Saddle  Mountain, 
at  an  altitude  of  about  9,000  feet.  This  whole  basin  is 
richly  watered  by  small  streams,  but  sheep  and  drought 
together  had,  during  1899,  devastated  the  above-timber 
country.  From  this  basin  as  a  base,  expeditions  by  foot 
were  made  for  many  miles  about,  over  the  surrounding 
mountains,  an  elevation  of  12,500  feet  being  reached  at 
several  points.  The  results  from  above  timber  were  very 
disappointing,  though  as  full  advantage  as  possible  was 
taken  of  the  richer  vegetation  below.  Below  timber  line 
these  mountains  are  richly  clothed  with  magnificent  forests 
of  spruce — principally  Picea  Engelmannii.  Deer  and  bear 
were  abundant  here  and  mountain  lion  frequent.  Black 
grouse  could  also  be  had  at  any  time.  At  this  time  should 
be  acknowledged  many  kindnesses  received  from  a  very 
affable  and  whole-hearted  gentleman,  Mr.  W.  R.  Black,  of 
Pagosa  Springs,  part  owner  of  the  promising  Baritone 
Wonder  and  Omaha  mines  near  Camp  Loraine.  He  gave 
freely  all  the  needed  information  as  to  trails,  topography, 
meteorology,  and  all  similar  matters.  Camp  at  this  point 
was  regretfully  broken  up  on  August  30. 

A  ten  days'  stop  at  Chama,  New  Mexico,  completed  the 
season's  work.  During  this  ten  days  a  trip  was  made  up 
on  Cumbres  Pass,  where  an  elevation  of  10,000  feet  was 
reached.  But  the  sheep  had  been  there  first. 

The  collecting  was  done  throughout  by  one  person.  It 
would  have  been  entirely  possible  to  have  accomplished  far 
more  had  the  season  and  other  conditions  been  more  favor- 
able. Whatever  success  was  attained  was  due  in  no  small 
measure  to  the  faithful  services  of  the  camp-hand,  an  Ala- 
bama negro  from  Prof.  Earle's  station  force.  This  man's

very  unusual  value  lay  not  so  much  in  his  great  strength 
and  endurance,  as  in  the  fact  that  he  would  do  exactly  as 
told. 

Throughout  the  field  work  constant  reference  was  made 
to  the  very  useful  and  minutely  exact  topographical  maps 
lately  issued  by  the  Geological  Survey,  as  well  as  to  those 
of  the  Hay  den  Survey.  Mention  should  also  be  made  of 
the  very  interesting  and  valuable  though  not  wholly  cor- 
rect map  in  the  Biennial  Report  of  the  Forest  Commissioner 
of  the  State  of  Colorado  for  the  years  1887  and  1888.

By  the  subjoined  enumeration  it  will  be  seen  that  Mr- 
Baker's  collection  of  1899  is  rich  in  new  species  of  Ascomy" 
cetes,  in  this  regard  surpassing  the  collection  made  by 
Baker,  Earle  and  Tracy  in  the  same  general  region  in  the 
year  1898.  The  present  list  of  species  would  have  been 
more  extensive  had  not  much  of  the  material  collected  on 
dead  stems  of  herbaceous  plants  in  early  spring  proven  im- 
mature and  thereby  indeterminable.  Those  of  the  same 
habitat  gathered  in  August,  and  even  in  July,  were  for  the 
most  part  in  good  condition.  This  is  especiall}<  true  of 
species  belonging  to  the  Mycospserellacese,  and  the  Pleo- 
sporaceae.  Specimens  belonging  to  those  families  in  which 
the  perithecia  on  hard-carbonaceous,  such  as  the  Amphi- 
sphseracise  and  Lophiostomatacese,  usually  contained  recog- 
nizable asci  and  spores  which  had  been  found  the  year 
before,  but  were  not  in  satisfactory  condition. 

Thanks  are  due  to  Dr.  J.  C.  Arthur  for  aid  in  connection 
with  the  Uredinales ;  to  Dr.  L.  M.  Underwood  for  determin- 
ing the  species  of  Polyporus,  and  to  Mr.  David  Griffiths  for 
careful  cultural  studies  of  the  Sordariacese.

smaller  spores,  but  more  particularly  in  the  cinnamon-brown 
of  the  crisped,  continuous  hairs  and  in  the  orange  disc.  In 
the  latter  species  the  color  is  "dirty  white,"  the  hairs  are 
septate,  and  the  disc  has  "no  shade  of  yellow."

able to  give  any  account  of  the  asci  and  spores.  JThis  new

This  differs  materially  from  all  other  specimens  of  Lepto- 
sphseria  found  on  Typha  in  this  country  in  the  decidedly 
smaller  spores  and  narrower  asci.  Our  specimens  have  the 
asci  about  60xl2/x  and  the  spores  only  20x5/-t,  while  in 
specimens  of  L.  typharum  (Desm.)  Karst.  the  asci  are 
60-80x20/4,  and  the  spores  25-30x7-8/4.  Our  measurements 
of  perithecia  asci  and  spores  agree  closely  with  those  pub- 
lished for  L.  Typhse,  but  in  our  specimens  the  perithecia  are 
often  densely  cespitose  in  clusters  of  6  or  8  to  20  forming 
double  or  single  lines  and  not  "scattered"  as  described  for 
the  European  specimens.

This  approaches  some  of  the  smaller  spored  forms  that 
have  been  referred  to  P.  herbarum.  By  some  it  would 
doubtless  be  considered  as  belonging  to  that  composite 
species  to  which  has  been  referred  material  from  all  the 
continents  and  on  hosts  belonging  to  most  of  the  larger 
families  of  flowering  plants.  Such  mixing  of  things  can 
serve  no  good  purpose  in  classification. 

A  number  of  fuscous  mycelial  threads  are  usually  to  be

On  dead  willow  twigs  at  Durango,  March  19.  Also  at

This  seems  to  be  the  spermagonial  stage  of  what  has  been 
called  Valsa  boreella  Karst.  A  similar  form  on  Salix  from 
Kansas  (N.  A.  F.  No.  3447)  has  been  called  Cytospora  nivea, 
but  our  specimens  are  certainly  not  connected  with  Valsa 
idvea.  The  exuded  spore-masses  are  much  the  color  of  those 
of  C.  chrysosperma,  but  they  are  much  less  copious  and  do  not 
tnke  the  form  of  a  tendril.  The  spores  too  are  slightly 
larger  than  in  that  species.

This  agrees  with  N.  A.  F.  No.  3448  on  Cornus  asperifolia 
from  Kansas,  which  is  named  as  above.  The  hard  car- 
bonaceous, frequently  simple  stroma  indicates  that  it  belongs

On  dead  stems  of  Pedicularis  racemosa,  near  Pagosa  Peak,

This  was  previously  collected  by  Mr.  Baker  on  Pedicu- 
laris, at  Four  Mile  Hill,  near  Steamboat  Springs  in  Northern 
Colo.,  July  22,  1896.  It  was  referred  by  Ellis  to  the  com- 
posite P.  herbarum.  It  seems,  however,  to  be  sufficiently 
distinguished  from  that  assemblage  of  forms  by  its  larger, 
scattered  and  not  gregarious  hycindia.  In  this  vast  genus 
spore  characters  alone  furnish  an  insufficient  guide  to  the

about  150-175/x*,  membranous,  of  distinctly  cellular  paren- 
chyma, cells  6-12/x,  averaging  8/4  in  diameter,  ostioles  simply 
perforate,  the  opening  about  20/4  in  diameter;  sporules 
numerous,  regularly  oval  or  subcylindric,  ends  broadly  ob-

March;  n.  34. 

This  striking  fungus  can  hardly  belong  in  the  genus 
Macrosporium.  Its  compact  growth  suggests  the  Tubercu- 
lariacise  rather  than  the  Dematiacese.  The  only  recognized 
genus  of  the  former  family  with  muriform  spores  is  Spegaz- 
zinia,  but  our  fungus  differs  widely  from  that  genus  in  habit 
and  in  that  the  corridia  are  not  borne  on  sterigmata  but  on 
the  ends  of  the  sporophores.

Common  on  dead  stems  of  Sambucus,  near  Pagosa  Peak,

This  is  easily  distinguished  from  T.  Sambucina  by  the 
larger  softer  sporodoche,  the  larger  thicker  conidiophores 
and  the  much  larger  conidia.  In  specimens  of  the  latter 
species  examined  from  Europe  and  from  Wisconsin  the 
conidia  are  only  5-6x1  J/^. 

TUBERCULARIA,  sp.  ?  On  dead  branches  of  oak,  Hermosa' 
30  March;  n.  74. 

This  is  a  very  peculiar  fungus.  The  large  2-3mm.  sporo- 
doches  swarm  with  motile  bacteria-like  bodies.  The  coni- 
diophores seem  to  be  only  8-12xl/n  and  variously  branched 
or  united.  The  conidia  are  about  2-3xl/u.  It  is  externally 
brown,  but  vermilion-red  within,  and  crumbling  to  a  red 
powder.  It  suggests  the  red  stroma  of  some  Endothia-like 
fungus  rather  than  a  Tubercularia,  but  no  perithecia  could 
be  detected.

GRAMINE^:. 

There  is  perhaps  no  section  of  the  Middle  West  which 
presents  more  interesting  or  important  agrostological  prob- 
lems than  does  this  field  of  our  1899  explorations  and 
researches.  The  pasturage  is  almost  everywhere  here  most 
excellent ;  and  even  the  alpine  grassy  slopes  of  vast  extent 
far  above  the  limit  of  trees  are  converted  into  a  sheep  pas- 
ture. And  the  still  richer  Piedra  Meadows  are  famed 
throughout  the  whole  southern  Rocky  Mountain  region. 
The  less  elevated  and  more  arid  parts  of  the  country  have 
also  their  own  grass  flora  of  much  importance,  and  this  sec- 
tion in  particular  calls  for  careful  investigation  and  experi- 
mentation in  relation  to  the  preservation  and  propagation 
of  its  forage  plants. 

In  the  determination  of  the  species  of  the  following  list, 
invaluable  service  has  been  rendered  by  Mr.  F.  L.  Scribner, 
to  whom  a  set  of  specimens  was  sent  for  identification,  and 
by  the  late  Mr.  T.  A.  Williams.  Later  Mr.  C.  L.  Shear  furn- 
ished some  important  additions  and  corrections.  The 
bibliographic  citations  and  one  or  more  alterations  in 
nomenclature  have  been  supplied  by  Dr.  Greene.  The 
somewhat  extensive  field  notes  are  my  own.

Eriocoma  cuspidata,  Nutt.  Gen.  i.  40.  Arboles,  June  ;  n. 
189.  One  of  the  very  earliest  of  vernal  grasses.  At  Her- 
mosa,  where,  among  the  dry  hills  and  sandy  banks,  it  is 
common,  we  found  it  in  March,  showing  a  short  growth  of 
fresh  green  leaves  that  seemed  to  be  eagerly  sought  by  cat- 
tle. The  species  is  catalogued  in  PL  Baker,  i.  42,  as  Ory- 
zopsis  cuspidata.

early  a  date,  large  fresh  bunches  of  this  grass,  approaching 
maturity  on  the  dry  mesa  banks.  It  would  undoubtedly  be 
a  grass  of  great  value  if  amenable  to  cultivation  in  this  its 
native  region.  But  no  attempt  seems  to  have  been  made  in

PROSPECTUS  FOR  THE  COU.ECTION  OF  1901. 

My  botanical  field  work  in  the  Rocky  Mountain  region,  begun  nine 
years  since,  will  be  continued  in  1901  and  1902,  with  better  facilities  and 
under  conditions  otherwise  more  promising  than  heretofore.  The  speci- 
mens will  be  of  better  quality.  The  determinations  will  be  made  by 
those  botanists  who  are  most  competent  to  deal  with  matter  from  the 
West;  thus  making  the  collections  authoritative,  as  representing  in 
herbaria  the  flora  of  the  several  regions  explored. 

In  1901,  the  summer  and  autumn  will  be  given  to  the  field  from  Mar- 
shall Pass  eastward  and  south  westward  to  the  boundary  lines  of  Colorado; 
a  field,  as  far  as  known,  exhibiting  many  peculiarites  as  to  plant  genera 
and  species,  and  therefore  of  the  highest  promise.  The  ground  will  be 
covered  as  carefully  as  possible,  at  all  elevations,  *.  e.y  from  4,000  to 
13,500  feet.  This  will  be  our  third  and  probably  the  concluding  series  of 
our  Colorado  plants. 

It  is  purposed  to  begin,  in  1902,  the  exploration  of  a  still  newer  field, 
that  of  the  more  westerly  State  of  Nevada ;  and  several  years  may  be 
devoted  to  that  field,  prosecuting  the  work  throughout  many  of  its 
isolated  and  almost  or  altogether  unexplored  mountain  ranges,  and  to 
the  western  and  southern  borders  of  the  State. 

Subscriptions  to  all  these  series  are  now  being  received,  and  should  be 
registered  as  early  as  possible ;  for  the  sets  go  out  to  subscribers  in  the 
order  of  time  recorded  for  the  subscription,  the  fullest  sets  to  the  earliest 
subscribers.  Arrangements  have  been  made  whereby  it  will  be  possible 
for  any  institution  to  obtain  these  sets.  Correspondence  is  solicited. 

A  few  short  sets  of  the  collections  by  Baker,  Barle  and  Tracy  in  1898 
are  still  available.  One  good  set  of  the  1899  collection,  but  lacking  the 
grasses,  sedges  and  rushes,  though  very  rich  in  the  new  species,  remains 
unsold.  Its  price  is  $73. 

The  distribution  of  mosses  and  liverworts  from  South  America  will  soon 
be  made.     These  include  many  new  species.

ITINERARY. 


ITINERARY. 

Plans  for  the  summer  months  of  1901  embraced  an  ex- 
amination of  the  flora  of  the  Gunuisori  watershed,  includ- 
ing the  region  from  Marshall  Pass  to  Grand  Junction,  with 
the  valleys  and  hills  adjoining  the  Gunnison  River  and  its 
principal  tributaries.  This  region  has  a  northwest  and 
southeast  extension  in  west  central  Colorado  and  includes 
areas  of  very  diverse  character,  both  topographical  and 
geological,  and  the  flora  varies  accordingly.  The  drainage 
area  is  a  part  of  that  of  the  Colorado  River  and  its  waters 
eventually  reach  the  Gulf  of  California. 

The  region  is  separable  into  three  distinct  areas:  The 
High  Mountain  Area,  the  Foothill  Area,  and  the  Desert 
Area.  On  the  extreme  east  lies  Mount  Ouray  and  its  com- 
panion peaks;  to  the  north  the  Elk  Mountains  of  numerous 
very  high  and  often  jagged  peaks,  and  to  the  south  the 
Cochetopa  Mountains — less  lofty  and  more  often  with 
rounded,  grassy  summits.  The  above,  with  that  portion  of 
the  San  Miguel  Mountains  about  the  headwaters  of  the 
Uncompahgre  River,  a  tributary  of  the  Gunnison,  and  the 
Grand  Mesa,  compose  the  High  Mountain  Area  of  this 
region. 

All  that  country  between  Jack's  Cabin,  Sargent's  and- 
Lake  City  on  the  one  hand,  to  Cerro  Summit  and  Ridg- 
way  on  the  other,  may  be  classed  as  Foothill  Area.  This 
is  a  country  of  comparatively  low,  rounded  hills  and  narrow 
valleys,  the  hills  covered  with  sage  brush  and  scattering 
pine  and  spruce,  the  valleys  with  alder,  willow  and  cotton- 
wood  along  the  streams,  and  with  frequent  rich  meadows. 

Passing  down  the  Gunnison,  the  river  just  below  Sapinero 

777-1 


11  PLANTS     BAKERIAN.E. 

enters  the  rocky  gorge  of  the  Black  Canon.  This  is  passa- 
ble for  the  Rio  Grande  Railroad  for  fifteen  miles  to  a  point 
near  Cimarron,  where  the  Cimarron  River  enters  from  the 
south.  Here  the  railroad  is  compelled  to  climb  up  through 
Cimarron  Canon  and  over  Cerro  Summit  to  seek  a  western 
outlet  by  way  of  the  Uncompahgre  Valley  to  Delta,  which 
is  again  on  the  Gunnison.  From  Cimarron  to  near  Delta 
the  Gunnison  runs  through  its  Grand  Canon,  so  deep  and 
narrow  and  with  such  precipitous  walls  as  to  be  quite 
inaccessible. 

Passing  westward  from  Cerro  Summit,  the  change  in 
character  of  country  and  of  flora  is  one  of  the  most  sudden 
and  most  remarkable  in  the  State  of  Colorado.  Cerro  Sum- 
mit is  a  huge  hill  covered  with  thickets  of  oak  scrub  and 
Amelanchier  (scattering  other  shrubs)  and  supplied  with  a 
rich  herbaceous  vegetation.  A  few  miles  to  the  westward 
and  a  few  hundred  feet  below,  say  at  Cedar  Creek,  one  is  in 
the  Desert  Area,  with  cedars,  pifion,  Sarcobatus,  Atriplex, 
and  a  characteristic  desert  flora.  From  this  point  to  the 
west  end  of  the  Grand  Mesa,  the  broad  Uncompahgre  Valley 
was  originally  almost  an  utter  desert.  It  is  flanked  on 
either  side  with  adobe  hills  or  gravelly  mesas,  sparingly 
clothed  with  cedars  or  entirely  naked,  the  bottoms  with 
Sarcobatus  and  its  companions,  and  along  the  stream  willows 
and  cotton  woods. 

From  Delta  to  Grand  Junction  the  Gunnison  runs 
through  its  Lower  Canon  which  is  broader  and  shallower 
than  the  Grand  Canon  and  flanked  by  barren  and  broken 
sandstone  hills,  in  some  places  closely  resembling  the  Colo- 
rado Canon  formation.  A  collection  of  the  curious  flora  of 
this  hot,  dry  Lower  Canon  was  made  within  seven  miles  of 
Deer  Run.  At  Grand  Junction  the  Gunnison  passes  into 
the  broad  valley  of  the  Grand  River,  which  is  also  desert 


ITINERARY.  Ill 

where  unirrigated.  Below  Grand  Junction  the  lowest  alti- 
tude in  the  State  is  reached. 

In  the  High  Mountain  and  Foothill*  Areas  the  rocks  are 
quite  largely  metamorphic  and  the  soils  are  constituted 
accordingly.  In  the  Elk  Mountains  near  Crested  Butte  and 
Ruby  there  are  extensive  outcroppings  of  slate  and  coal. 
In  these  mountains  collections  were  made  at  Crested  Butte, 
Rogers,  Keblar  Pass  and  Ruby. 

The  Elk  Mountains  are  a  wonderful  range  of  high, 
closely  set,  jagged  peaks,  well  watered,  richly  clothed  with 
spruce  forests  and  other  vegetation — undoubtedly  richer  in 
this  respect  than  any  other  mountains  of  Colorado.  They 
are  remote,  rarely  visited,  and  together  form  the  richest  and 
most  promising  high-mountain  botanical  field  in  the  State. 
Deep  forests,  meadows,  open  glades  and  parks,  dripping 
cliffs,  and  springs  and  streams  everywhere,  altogether  furnish 
a  most  remarkable  field  for  plants  of  all  groups. 

Later  on  when  our  Botanical  Gardens  and  Universities 
establish  their  substations  for  Experimental  Ecology  and 
similar  work,  there  should  certainly  be  one  here. 

In  the  High  Mountain,  Area  collections  were  also  made 
at  and  near  Marshall  Pass,  at  Carson  in  the  Cochetopas,  at 
Ouray  and  on  the  surrounding  hills  in  the  San  Miguels,  and 
on  the  summit  of  the  Grand  Mesa. 

In  the  Foothill  Area,  collections  were  made  at  Jack's 
Cabin,  Sargent's,  Doyle's,  Gunnison,  lola,  Sapinero,  the 
Black  Canon,  Cimarron,  at  Van  Boxle's  Ranch  above  Cirnar- 
ron,  on  Poverty  Ridge  near  Cimarron,  on  the  Black  Mesa  at 
the  head  of  Crystal  Creek,  and  on  Cerro  Summit. 

In  the  Desert  Area  collections  were  made  at  Cedar  Creek, 
Montrose,  Cedar  Edge,  Deer  Run,  and  Grand  Junction. 

*  This  term  may  be  objected  to  as  not  equivalent  to  the  Foothills  on 
the  east  slope.  But  neither  would  the  Desert  Area  hei^  be  equivalent  to 
the  Plains  on  the  east. 


IV  PLANTS     BAKERIAN.E. 

While  the  localities  given  are  not  many  in  number,  still, 
around  them  and  between  them  a  good  deal  of  ground  was 
covered.  Tramps  were  made  around  each  point  for  a  radius 
of  several  miles  and  most  places  were  visited  more  than 
once  during  the  three  months.  Walks  were  also  made  be- 
tween Ruby  and  Keblar  Pass,  between  Keblar  Pass  and 
Crested  Butte  (seven  miles),  between  Crested  Butte  and 
Jack's  Cabin  (fifteen  miles),  between  Marshall  Pass  (alt. 
10,800  ft.)  and  the  top  of  Mount  Ouray  (14,000  ft.),  and  to 
the  top  of  Little  Ouray,  between  Lake  City  (8,000  ft.)  and 
Carson  (11,500  ft.)  and  return  (thirty-two  miles),  between 
Cimarron  and  top  of  Poverty  Ridge  and  return  (ten  miles) 
three  times,  between  Cimarron  and  the  Black  Mesa  and  re- 
turn (sixteen  miles),  four  times  between  Cimarron  and  Cerro 
Summit  (five  miles),  through  the  fifteen  miles  of  the  Black 
Canon  three  times,  from  Cerro  Summit  to  Cedar  Creek 
(seven  miles)  from  Grand  Mesa  Lakes  to  Cedar  Edge  (seven 
miles),  from  Telluride  to  Ouray  (twenty  miles, over  a  divide 
rising  to  13,500  ft.),  and  between  Deer  Run  and  Kanah 
Creek  (seven  miles)  three  times.  This  is  over  and  above 
the  local  work  around  all  the  points  mentioned.  So  the 
plants  obtained  will  represent  the  phanerogamic  flora  fairly 
well.  Getting  into  the  field  so  late  and  doing  all  the  work 
alone  made  it  impossible  to  give  the  necessary  attention  to 
the  collection  of  the  cryptogams.  But  the  region  is  rich  in 
them.  The  fleshy  forms  were  noted  especially  in  the  Elk 
Mountains,  where  they  were  abundant  even  up  into  the 
highest  timber.  Such  fungi  and  mosses  as  intruded  them- 
selves on  the  attention  were  collected. 

Two  points  in  the  subalpine  country  should  be  especially 
noted — the  Grand  Mesa  and  Van  Boxle's  Ranch.  The 
Grand  Mesa  is  a  high  elongated  plateau  extending  north- 
westerly from  the  West  Elk  Mountains  to  the  Gunnison 


ITINERARY.  V 

below  Delta.  It  is  a  remarkable  place.  The  top  is  well 
watered,  with  many  streams  and  beautiful  lakes  and  with 
rich  forests  and  open  parks.  About  the  base  lies  the  desert. 
The  Grand  Mesa  can  be  readily  reached  by  a  twenty-five 
mile  drive  from  Delta. 

Van  Boxle's  Ranch  is  twelve  miles  above  Cimarron  on 
the  headwaters  of  the  Little  Cimarron.  One  could  scarcely 
find  a  richer  or  more  beautiful  mountain  locality  than  this, 
surely  not  one  more  remote  or  less  known.  Splendid  trout 
fishing  is  not  one  of  the  least  of  the  many  attractions. 

Here  should  be  detailed  those  plants  which  were  observed 
but  for  various  reasons  were  not  collected.  The  high  spruce 
woods  were  composed  almost  entirely  of  Picea  Englemanni 
and  Pseudolsuga.  Along  the  lower  border  of  the  spruce  are 
extensive  thickets  of  quaking  aspen,  some  of  the  trees  often 
reaching  very  good  size.  Here,  also,  in  favorable  places 
bear  berry  (Arctostaphylos  uva-ursi)  is  common.  Through- 
out the  foothill  and  mountain  country  Alnus  was  frequent 
along  the  streams,  and  the  red-berried  Sambucus  was  occa- 
sional in  the  higher  altitudes.  The  scrub  oak  thickets  so 
common  in  the  foothill  country  have  already  been  men- 
tioned. Wet  swales  in  the  lower  altitudes  were  usually 
filled  with  Typha,  and  often  contained  colonies  of  Scirpus 
occidentalis.  One  of  the  poison  oaks  (Rhus)  was  common 
in  the  bottoms  throughout  the  lower  altitudes,  but  ex- 
treme susceptibility,  induced  by  a  most  troublesome  expe- 
rience in  the  swamps  near  Mobile,  Alabama,  led  me  to 
give  it  a  wide  berth.  Again  cattle  were  seen  browsing 
it,  apparently  with  relish.  Helianthus  petiolaris,  Plantago 
major,  Salsola  kali,  Solanum  nigrum,  Xanthium  strumarium, 
Amarantus  blitoides,  and  A.  retroflexus,  occurred  on  almost 
all  cultivated  areas,  along  roads  and  railroads,  and  in  rail- 
road yards.  In  the  Gunnison  Valley  the  Russian  Thistle 


VI  PLANTS     BAK  BRIANS 

is  almost  entirely  confined  as  yet  to  the  yards  and  along 
the  right  of  way  of  the  railroad.  The  section  men  have 
instructions  to  destroy  it,  but  it  was  found  that  few  of  them 
were  acquainted  with  it.  In  its  younger  states  it  is  soft  and 
succulent,  and  cattle  and  horses  eat  it  freely.  Humulus 
lupulus  occurs  occasionally  in  the  bottoms,  and  a  few  plants 
of  Panicum  crus-galli  were  seen  at  Grand  Junction.  Cereus 
phoeniceus  and  one  of  the  ordinary  yellow-flowered  prickly 
pears  are  common  throughout  the  foothill  country.  On 
gravelly  hillsides  in  the  Desert  Area,  Opuntia  arborescens  is 
not  uncommon.  Phleum  alpinum  and  Poa  alpina  were 
abundant  throughout  the  alpine  region.  A  few  immature 
plants  of  Melica  bulbosa  were  seen  on  Poverty  Ridge.  Above 
Ouray  a  few  plants  of  Artemisia  franserioides  were  observed. 
The  agricultural  possibilities  of  this  region  as  it  is  de- 
scribed above  would  not  appear  very  promising.  On  the 
contrary,  they  are  very  great.  Even  the  naked  adobe  soil 
possesses  a  wonderful  fertility  and  requires  but  water  to 
make  it  yield  richly.  Even  now  there  are  ranches  where 
small  ditches  could  be  taken  out,  all  along  the  Gunnison 
except  in  the  narrow  canons,  and  likewise  along  the  Un- 
compahgre.  Near  Crested  Butte  (8,878  ft.)  the  altitude  is 
too  great  for  common  garden  vegetables  and  fruits,  but  the 
natural  meadows  in  the  vicinity,  full  of  native  grasses  and 
sedges,  have  been  improved  and  produce  heavily.  At  Jack's 
Cabin  (about  8,300  ft),  fifteen  miles  below  Crested  Butte  one 
may  see  beautiful  fields  of  alfalfa  and  timothy,  and  here  are 
raised  radish  and  lettuce  and  other  very  hardy  and  quickly 
maturing  garden  vegetables.  Sargent's  (between  Gunnison 
and  Marshall  Pass)  is  much  like  Jack's  Cabin  in  this  respect. 
Doyle's,  between  Guunison  and  Sargent,  was  found  to  be  a 
very  interesting  locality  on  account  of  the  considerable  per- 
centage of  alkali  in  the  bottom's  soil.  The  meadows  here 


ITINERARY.  Vll 

were  consequently  not  as  rich  and  were  overrun  with  the 
worthless,  even  injurious,  grass  locally  known  as  "fox-tail." 
A  number  of  distinctly  halophytic  plants  were  present  such 
as  Trigloclin  maritima  and  a  Plantago. 

At  Guiinison  (7,680  ft.)  are  some  beautiftili  ^eacjpws, 
though  many  are  filled  with  a  most  astonishihg  arra^of 
native  plants.  When  these  are  in  bloom;,  thfc1  ]£riger^nfe,\ 
Pedicularis,  Castilleias,  Crepis  and  many  others,  present  a 
very  beautiful  sight.  Barley,  oats  and  red  clover  do  well 
here,  and  better  examples  of  radish,  lettuce,  carrots,  turnips, 
potatoes,  rhubarb,  cabbage,  etc.,  would  be  hard  to  find.  It 
is  probable  that  some  of  the  small  fruits  would  prove  a  great 
success  at  this  point. 

Coming  down  out  of  the  foothill  country  and  entering 
the  desert  above  Montrose,  one  finds  beautiful  orchards  and 
broad  green  fields  where  the  ground  has  been  irrigated,  and 
portions  now  have  the  appearance  of  a  prosperous  agricul- 
tural district.  It  is,' however,  near  Delta  (about  5,000  ft.) 
and  neighboring  towns  that  the  fruits  are  grown  to  greatest 
perfection.  Here  are  produced  pears,  peaches,  apples,  plums, 
cherries  and  other  fruits  which  cannot  be  excelled.  Grand 
Junction  is  also  the  center  of  a  great  fruit  country. 

There  is,  in  this  Gunnison  region,  a  vast  natural  supply 
of  water  from  the  high  mountains  and  vast  areas  of  land 
which  that  water  may  yet  be  carried  to  in  ditches,  so  that 
the  possibilities  before  the  region  are  almost  unlimited. 
The  day  is  coming  when  the  lower  Gunnison  valley,  now 
largely  a  desert,  will  be  one  of  the  richest  agricultural  re- 
gions in  the  United  States. 

Thousands  of  sheep  are  pastured  during  summer  in  the 
lower  foothills.  Higher  up  many  cattle  may  be  found, 
though  there  is  rich  unoccupied  range  for  many  times  the 
number  now  there. 


Vlll  PLANTS     BAKERIAN^E. 

The  field  work,  all  done  between  June  1st  and  September 
1st  by  one  person,  resulted  in  the  collection  of  above  25,000 
specimens  with  notes  on  each  species.  Also,  photographs 
were  taken  of  all  the  characteristic  ecological  associations. 
As  rip  ^previous  years  the  work  would  have  been  largely 
impossible  put /or  the  co-operation  and  encouragement  of 
,J)r.;  15.;  L.  ^Greene,  whose  remarkable  knowledge  of  the 
American  field  directed  operations  in  these  most  remote 
localities,  even  to  definite  hills,  valleys  and  meadows. 

Here  also  should'  be  acknowledged  the  great  kindness  of 
Mr.  E.  T.  Jeffery,  President  of  the  D.  &  R.  G.  System,  and 
of  other  officials  of  the  Road,  without  whose  assistance  some 
of  the  work  would  have  been  quite  impossible.  A  faithful 
boy,  Ed.  Dundin,  did  the  camp  work,  and  most  of  the 
changing  of  driers,  though  the  work  of  first,  putting  plants 
into  press,  taking  out  those  finally  dried,  cleaning,  bundling, 
writing  labels  and  separating  a  study  set,  necessarily  de- 
volved on  the  collector.

RANUNCULACE.E. 


EXPLANATORY. 

Mr.  Bakers'  botanical  exploration  of  the  Gunnison  Water- 
shed in  the  summer,  of  1901,  has  already  proven  a  remarkable 
success,  both  as  to  the  number  and  quality  of  the  specimens; 
while  the  wealth  of  new  species  is  even  greater,  I  think, 
than  was  obtained  in  other  sections  of  southern  Colorado 
either  by  Mr.  Baker  in  1899,  or  by  Baker,  Earle  and  Tracy 
in  1898.  Many  of  the  new  things  in  those  two  earlier 
collections  are  still  unpublished;  this  being  largely  due  to 
my  having  undertaken  to  publish  full  lists  of  those  collec- 
tions, and  in  due  taxonomic  sequence. 

Pending  the  completion  of  volumes  I  and  II  of  the 
PLANTS  BAKERIAN.E,  I  propose  giving,  as  a  first  instalment 
of  volume  III  a  somewhat  miscellaneous  congeries  of 
paragraphs  dealing  with  new  or  otherwise  interesting 
species;  in  this  absolving  myself  from  the  obligation— more 
fanciful  than  real — of  following  any  particular  sequence  of 
Families.  Any  difficulty  which  this  want  of  order  may 
seem  to  entail  upon  students  of  the  sets,  will  be  obviated 
by  an  index  to  the  genera  treated,  if  not  even  to  the  species.

RANUNCULACK^e. 

RANUNCULUS  EREMOGENES,  Greene,  Eryth.  iv.  121. 
Abundant  in  a  small  pond  within  the  Black  Canon,  n.  204; 
quite  typical.  In  publishing  this  interesting  analogue  of

the  Old  World  R.  sceleratus,  I  credited  it  to  no  station  more 
southerly  than  middle  Colorado.  The  present  record  would 
therefore  be  a  considerable  extension  of  its  range.  But  my 
herbarium  shows  that  I  myself  collected  it  in  1889  as  far 
south  as  Trinidad,  on  the  extreme  southern  verge  of  Colo- 
rado. Mr.  Heller  has  more  recently  distributed  it  from  Rio 
Arriba  Co.,  New  Mexico;  and  I  may  here  note  that  in  1898 
I  found  plenty  of  it  along  the  muddy  margin  of  a  lake  in 
southern  Minnesota  not  far  from  Windom,  this  being  its 
most  easterly  habitat  so  far  as  known. 

RANUNCULUS  EREMOGENES,  var.  PILOSULUS.  Much  smaller 
than  the  type,  with  several  subequal  ascending  stems  5  or 
6  inches  high;  herbage  of  a  deeper  green  and  sparsely 
pilose-pubescent;  receptacle,  heads  and  achenes  much  as  in 
the  type,  but  all  smaller. 

In  damp  places  above  Gunnison,  17  July,  n.  454.  Quite 
different,  except  as  to  height  and  mode  of  growth,  from  my 
var.  degener  of  the  same  species. 

RANUNCULUS  PURSHII,  Richardson.  Fine  large  speci- 
mens, growing  in  ponds  near  Gunnison,  n.  669;  differing 
from  the  high-northern  type  in  failing  to  show  the  very 
narrowly  dissected  submersed  leaves.  A  so-called  "R  Pur- 
shii"  of  Mr.  Baker's  collecting  at  Fort  Collins,  Colo.,  in  1896 
is  clearly  R.  eremogenes. 

RANUNCULUS  UNGUICULATUS,  Greene,  Pitt.  iv.  142.  Two 
numbers  of  this,  both  from  the  Grand  Mesa;  228,  much 
smaller  than  the  type  specimens  and  too  young;  234  is 
more  mature,  and  large  enough  to  represent  the  species  well. 

RANUNCULUS  OREOGENES.  Of  the  size  and  habit  of  R.  ellip- 
ticus,  with  even  larger  and  coarser  roots,  but  foliage  of  dif- 


RANUNCULACE^E.  3 

ferent  form  and  texture,  being  much  firmer  and  scarcely 
ucculent,  the  lowest  leaves  narrowly  ovate-lanceolate,  those 
next  succeeding  them  linear-elliptical,  the  blades  about  1J 
inches  long,  the  petioles  about  as  long,  the  mostly  solitary 
cauline  like  the  others  but  closely  sessile,  all  vivid-green 
and  reticulate-venulose  above,  pale  beneath,  even  whitish, 
all  perfectly  entire;  scapiform  peduncles  decumbent,  simple 
and  1-flowered,  or  with  one  or  two  1-flowered  branches: 
calyx  and  corolla  not  seen:  head  of  achenes  ovate;  achenes 
pubescent,  the  body  suborbicular,  the  beak  rather  prominent? 
curved. 

At  Cerro  Summit  above  Cimarron,  7  June,  n.  50;  occur- 
ing  on  open  hillsides,  but  past  flowering. 

In  addition  to  the  above,  the  collection  exhibits  the 
following  less  noteworthy  Ranunculi:  R.  reptans,  Linn.,  n. 
464;  R.  inamoenus,  Greene,  nn.  235,  350;  R.  Macounii,  Britt., 
n.  562,  and  R.  Macauleyi,  Gray,  n.  319. 

BATRACHIUM  TRICHOPHYLLUM,  Bossch.,  n.  320. 

CYRTORHYNCHA  RUPESTRIS.  Stems  very  slender  and  few- 
flowered,  more  than  a  foot  high;  biternate  foliage  ample 
and  of  more  than  half  the  height  of  the  stems;  flowers 
mostly  only  5  or  6,  on  long  slender  pedicels  and  very  small: 
petals  about  5,  variable,  some  obovate  and  sessile,  others 
(transitional  to  stamens)  with  smaller  blade  and  long  claw: 
achenes  few,  short  and  of  almost  elliptic  outline,  the  ribs 
prominent,  but  more  or  less  confluent  and  inclined  to  form 
narrow  reticulations. 

On  moist  cliffs  in  the  Black  Canon,  20  June,  n.  198.  An 
excellent  new  species  of  an  interesting  genus,  this  has  the 
aspect  of  C.  neglecta,  of  northern  Colorado,  but  not  at  all 
either  its  flowers  or  fruits. 


4  PLANTS     BAKERIAN^E. 

CALTHA  CHIONOPHILA,  Greene,  Pitt.  iv.  80.  Two  repre- 
sentations of  this;  n.  227,  from  the  Grand  Mesa,  shows  con- 
stricted but  not  dentate  foliage,  while  n.  408,  from  Carson, 
has  the  leaves  smaller,  more  rounded,  and  notably  dentate. 

TROLLIUS  ALBIFLORUS,  Rydb.  Fl.  Mont.  152.  Under  n. 
221  we  have  excellent  flowering  specimens  of  this  fine  plant 
which  Mr.  Rydberg  has  well  separated  altogether,  in  name 
and  rank,  from  T.  laxus. 

DELPHINIUM  NELSONII,  Greene.  On  open  hillsides  at 
Cerro,  n.  52,  the  usual  form;  n.  216,  the  largest  and  most 
showy  specimens  yet  seen,  said  to  be  abundant  in  open 
parks  at  Van  Boxle's,  abo.ve.Cimarron. 

DELPHINIUM  DUMETORUM.  Near  the  last,  but  more 
slender  and  commonly  2  feet  high  or  more;  leaves  remote 
and  with  fewer  and  broader  segments;  herbage  glabrous; 
ramifications  of  the  root  more  slender  and  disconnected: 
flowers  smaller  and  less  widely  expanding,  though  with 
ispur  longer  and  more  slender,  acutish  and  strongly  curved 
downward  at  the  end,  the  color  of  the  whole  flower  a  pale 
lavender-blue:  follicles  puberulent,  shorter  and  more  widely 
spreading  than  in  D.  Nelsonii 

On  dry  hills,  among  shrubbery  above  Cimarron,  6  June, 
n.  35;  growing  quite  apart  from  D.  Nelsonii,  which  occupies 
open  grassy  ground  at  higher  elevations. 

DELPHINIUM  QUERCETORUM.  Resembling  D.  glaucum, 
perhaps  as  tall,  with  equally  leafy  stem  and  narrow  con- 
densed raceme;  herbage  pale  and  glaucescent,  but  only  the 
stem  and  petioles  truly  glabrous,  the  leaves  villous-puber- 
ulent,  their  3  to  5  segments  broad -cuneiform  and  3-lobed,  not 
toothed  ;  rachis  of  the  spike  strongly  hirtellous,  the  pedicels 


CRUCIFEM;.  5 

most  so,  and  the  hairs  of  these  viscid  and  mostly  gland- 
tipped:  small  flowers  very  dark  blue-purple,  the  sepals  rugu- 
lose  and  together  with  the  slender-conical  turgid  straight 
ascending  spur  rather  rough-hairy :  ovaries  densely  villous. 
Common  among  oaks  at  Cerro,  12  July,  n.  412.  At  first 
glance  this  appears  much  like  true  D.  glaucum,  though  the 
leaves  are  much  less  divided  than  is  usual  in  that  species, 
and  the  flowers  are  much  darker ;  but  a  lens  reveals  the 
abundant  short-hairiness  of  the  foliage ;  and  the  even 
stronger  pubescence  of  the  rachis  is  of  a  character  quite 
peculiar.  Moreover,  this  is  a  dry-land  plant,  whereas  D. 
glaucum,  grows  only  in  wet  places. 

ACONITUM  BAKERI.  Stern  stoutish,  erect,  simple  and 
rather  strict,  2  feet  high,  the  whole  upper  portion  of  the 
plant,  even  to  the  flowers,  villous  hirsute  with  brownish 
hairs,  some  of  them  gland-tipped  :  lower  parts  glabrous,  the 
lowest  leaves  5-parted  and  the  cuneate  divisions  doubly 
about  3-cleft :  raceme  compact:  hood  f  inch  high,  the  gal- 
eate  portion  rounded,  scarcely  higher  than  broad,  much 
shorter  than  the  downward  portion,  the  beak  broadly  subu- 
late, projecting  horizontally;  follicles  about  4,  glabrous. 

At  10,000  feet  near  Marshall  Pass,  19  July ;  said  to  be 
common  in  wet  places.'  The  only  American  species  with 
dense  almost  spicate  and  strict  inflorescence,  the  sepals  and 
petals  remarkably  pubescent.  It  is  the  only  Aconite  of  this 
year's  collection.

DRABA  GRAMTNEA.  Perennial,  the  much  branched  stems 
3  to  5  inches  high,  the  older  portions  thickly  clothed  with 
long  dry  chaffy  remains  of  the  leaves  of  other  seasons : 
leaves  of  the  season  linear  and  grassy,  almost  as  long  as  the

short-peduncled  loose  and  rather  few-flowered  racemes, 
glabrous  above  the  middle,  but  below  it  loosely  ciliate  with 
simple  hairs :  sepals  yellow ;  petals  pale-yellow  :  filaments 
abruptly  and  widely  dilated  at  base;  young  pods  ovate, 
acute,  surmounted  by  a  conspicuous  style,  few-ovuled. 

A  most  remarkably  chaffy  and  grassy-looking  Draba  of 
alpine  habitat,  found  near  Carson,  2  July,  n.  296.  Its  near- 
est affinity  would  seem  to  be  D.  chrysantha. 

DRABA  OXYLOBA.  Perennial,  tufted,  the  several  and 
quite  simple  flowering  stems  or  branches  decumbent,  leafy 
to  near  the  middle,  thence  racemose,  8  to  18  inches  high; 
foliage  and  stem  not  at  all  canescent,  scarcely  even  pale, 
nevertheless  roughened  everywhere  by  an  sparse  indument 
of  sessile  and  uniformly  4- parted  hairs:  basal  leaves  1  to 
2  inches  long,  oblanceolate,  petiolate,  remotely  dentate  or 
else  entire,  the  petioles,  at  least  near  the  base,  with  a  few 
scattered  marginal  simple  and  setaceous  hairs;  cauline 
leaves  ovate  to  oblong-lanceolate,  commonly  hear  an  inch 
long,  sessile,  dentate:  sepals  and  petals  both  golden-yellow, 
the  former  with  scattered  short  mostly  simple  (rarely  forked) 
hairs:  pods  not  twisted,  oblong-linear  to  elliptical,  4  or  5 
lines  long,  acute  at  each  end,  pointed  with  a  style  of  less 
than  one  line ;  pedicels  slightly  ascending,  longer  than  the 
pods. 

At  Van  Boxles'  Ranch  above  Cimarron,  in  open  parks, 
n.  382 ;  also  at  Sargents,  in  meadows,  n.  351 ;  distin- 
guished from  all  its  allies  by  a  pubescence  of  cruciform 
hairs. 

DRABA  BAKERI.  Rather  slender  yellow-flowered  per- 
ennial, the  several  erect  stems  4  to  10  inches  high:  tufted 
radical  leaves  about  an  inch  long,  oblanceolate,  short-petio- 
late,  entire,  acutish,  cinereous,  at  least  when  young,  with

stellate  pubescence,  the  stem  and  inflorescence  greener,  the 
pubescence  more  sparse,  mostly  of  forked  or  3 -branched 
hairs,  but  with  some  much  longer  and  perfectly  simple  ones 
interspersed:  cauline  leaves  lanceolate,  serrate-toothed,  ses- 
sile: fruiting  raceme  loose,  with  leafy  bracts  subtending  the 
lower  pedicels :  flowers  small;  sepals  green,  notably  bristly- 
hairy  at  apex;  petals  yellow,  scarcely  twice  the  length  of 
the  sepals:  pods  erect,  short-pedicellate,  narrowly  elliptical, 
pubescent  on  the  face  with  more  or  less  forked  and  appressed 
hairs,  but  the  margins  quite  hirsutulous  with  mostly  simple 
ones:  style  short. 

Near  the  limit  of  trees,  in  the  mountains  near  Carson, 
n.  316.  An  ally  of  D.  streptocarpa,  the  pods  doubtless  more 
or  less  twisted  when  mature.  ^  .„  r  . ,  r 

DRABA  NITIDA.  Annual,  very  erect  and  strict^  simple. ctt; 
with  a  few  shorter  racemes  from  near  the  base,  the  whole 
plant  often  10  to  14  inches  high,  racemose  almost  from  the 
base,  and,  except  at  base,  glabrous,  deep-green  and  shining: 
leaves  in  a  comparatively  small  radical  tuft,  the  longest 
barely  an  inch  long,  oblong-lanceolate,  obtuse,  entire,  the 
outer  narrowed  at  base  but  hardly  petiolate,  sparsely  sub- 
stellate-pubescerit,  the  margins  loosely  bristly-ciliate;  cauline 
few,  oblong-ovate,  entire,  sessile :  pedicels  3  or  4  lines  long, 
ascending,  the  oblong-linear  acutish  often  somewhat  in- 
curved glabrous  pods  about  as  long:  flowers  small,  yellow, 
the  green  sepals  more  or  less  pilose,  as  is  also  the  base  of 
the  stem:  style  none. 

Abundant  on  moist  open  ground  at  10,000  feet  above 
Marshall  Pass,  19  July,  n.  492.  A  less  luxuriant  state  of 
the  same  was  collected,  also  by  Mr.  Baker  at  Cameron  Pass, 
northern  Colorado,  at  9,800  feet,  in  July,  1896.  The  plant 
is  one  which  has  been  referred  erroneously  to  D.  stenoloba. 


8  PLANTS     BAKERIAN.E. 

ARABIS  DEMISSA.  Low  and  slender,  the  racemose  steins 
or  peduncles  only  5  to  8  inches  high,  but  the  caudex  large 
in  comparison,  stout  and  lignescent,  not  .branched,  or  the 
branches  not  obvious,  bearing  a  dense  tuft  of  very  narrowly 
oblanceolate  glaucescent  leaves,  which  are'  glabrous  except 
for  a  few  setose  hairs  on  the  margin  at  the  base  of  the  pe- 
tiolar  portion:  peduncles  several,  with  2  or  3  subauriculate 
sessile  bracts  below  the  raceme,  this  (seen  in  fruit  only) 
loose,  the  purplish  and  glaucous  pods  narrowly  linear,  1  to 
1J  inches  long,  deflexed  on  very  short  pedicels:  seeds  in 
one  row,  suborbicular,  not  winged,  though  with  more  than 
the  hint  of  a  scarious  margin  on  at  least  one  side. 

A  few  specimens  of  this  interesting  and  strongly  charac- 
terized; new;  species  were  gathered  from  among  the  stones  of 
a  dry  'river  bed  near  Cimarron,  4  June.  They  bear  the 
jariYnbie?  1fr,;'of  .the  collection,  but  are  not  in  quantity  for 
distribution  in  the  sets. 

ARABIS  STENOLOBA.  SufTrutescent  as  to  the  branching 
caudex,  the  slender  flowering  stems  less  than  a  foot  high, 
tufted  basal  leaves  and  those  of  sterile  branches  of  the 
caudex  oblanceolate,  entire,  less  than  an  inch  long,  both 
faces  hoary  with  a  minute  stellate  tomentum  :  floriferous 
branches  with  scattered  small  leaves  below  the  raceme,  this 
short  and  few-flowered ;  sepals  purplish,  stellate-pubescent, 
as  are  also  the  pedicels  and  the  stems,  petals  white,  twice 
the  length  of  the  sepals:  pods  very  narrowly  linear,  1  to  1J 
inches  long,  obtuse,  glabrous,  suberect  on  almost  filiform 
pedicels  of  J  to  J  inch. 

On  stony  hillsides  above  Cimarron,  n.  21.  Plant  with 
much  the  habits  and  foliage  of  A.  eremophila,  but  the  pubes- 
cence different,  the  fruit  more  so. 

THELYPODIUM    BAKERI.     Biennial,  with    several   widely 


VIOLACE^E.  9 

divergent  stems  from  amid  the  tuft  of  spreading  basal 
leaves;  herbage  glabrous,  except  some  hirsute  hairiness  at 
base  of  stem,  and  very  glaucous :  radical  leaves  petiolate, 
cauline  numerous,  narrowly  cordate-ovate,  sessile  and  clasp- 
ing, entire,  an  inch  longer  more:  flowers  white,  the  greenish 
sepals  somewhat  spreading,  the  petals  with  broad  claw  and 
spreading  spatulate-obovate  limbs :  spreading  pedicels  of  the 
pod  very  slender,  the  pod  itself  narrow,  not  stipitate,  an  inch 
long  or  more. 

Stony  hillsides  at  Cimarron,  6  June,  n.  32.  This  is  a 
very  near  ally  of  Miss  Eastwood's  T.  aureum,  but  its  flowers 
are  white,  and  the  pods  are  not  stipitate. 

THELYPODIUM  LILACINUM.  Biennial,  two  or  three  feet  high 
with  rather  many  ascending  branches  from  near  the  base, 
all  racemose  at  the  end;  herbage  deep-green  and  glabrous; 
basal  leaves  2  or  3  inches  long,  spatulate-oblong,  entire  or 
repand,  cauline  reduced,  lanceolate  to  nearly  linear:  flowers 
corymbosely  crowded,  but  the  raceme  lengthened  in  fruit 
to  4  or  5  inches;  sepals  erect,  rich  lilac-purple,  of  less  than 
half  the  length  of  the  spatulate-linear  petals,  these  at  first 
white  but  soon  changing  to  the  lilac  of  the  sepals:  pods 
slender,  torulose,  1J  inches  long,  scarcely  stipitate,  slender- 
beaked. 

At  Doyle's,  n.  635.  Related  to  T.  integrifolium,  but  of  dif- 
ferent habit,  with  different  inflore.scen.ee,  and  peculiarly 
handsome  flowers. 

VIOLACE^:. 

Only  the  genus  Viola  is  represented;  but  that  in  an  inter- 
esting array  of  species  by  far  the  greater  number  of  which 
are  absolutely  new.

10  PLANTS     BAKERIAN,E. 

V.  RETROSCABRA,  Greene,  Pitt.  iv.  290,  very  recently  pub- 
lished, is  represented  by  the  two  numbers  68,  144,  both 
from  near  Cimarron.  This  and  the  three  new  ones  next 
succeeding  are  of  the  natural  group  represented  by  the  Old 
World  V.  canina. 

V.  STENANTHA.  A  multiciptal  and  csespitose  dwarf,  form- 
ing mats  2  or  3  inches  broad,  little  more  than  1  inch  high ; 
herbage  very  minutely  and  sparingly  scabro-puberulent, 
the  angles  of  the  petioles  more  obviously  and  retrorsely  so : 
leaves  deltoid-ovate  to  oval,  little  more  than  J  inch  long, 
rather  fleshy,  lightly  crenate,  usually  tapering,  though 
abruptly,  to  the  petiole:  peduncles  about  equalling  the 
leaves,  bearing  conspicuous  subulate-linear  bractlets  near 
the  flower,  sepals  large  for  the  flower,  oblong-linear,  acute, 
glabrous,  not  scarious-naargined:  corolla  dark-blue,  about 
5  lines  long  including  the  very  long  and  narrow  somewhat 
hooked  spur,  very  narrow,  the  petals  not  widely  expanding, 
the  keel  broad j  the  others  narrow. 

On  the  Grand  Mesa,  23  June,  n.  230.  A  species  very 
well  characterized  by  its  long  and  narrow  long-spurred 
dark-blue  corolla. 

V.  DEMISSA.  Scarcely  larger  than  the  last,  but  rhizoma- 
tous,  the  rootstocks  chaffy  with  the  persistent  sere  and 
brown  stipules  of  a  preceding  year:  leaves  J  inch  long,  on 
petioles  of  about  an  inch,  round-ovate  to  deltoid-ovate  and 
oval,  crenate,  glabrous:  peduncles  much  exceeding  the 
leaves,  bibracteolate  towards  the  middle:  sepals  oblong- 
linear,  asute;  corolla  nearly  J  inch  long  including  the 
long  obtuse  cylindric  spur,  the  petals  subequal,  widely  ex- 
panding, violet  above  the  middle,  white  below,  and 
marked  with  purple  veins.

VIOLACE^;.  11 

Pass,  19  July,  n.  501.  What  is  probably  the  same  alpine  or 
subalpine  violet  was  collected  by  Mr.  Baker  at  Cameron 
Pass  in  northern  Colorado,  as  long  ago  as  1896.  •  It  is 
also  represented  in  C.  S.  Sheldon's  n.  277,  obtained  at 
Berthoud  Pass  in  middle  Colorado,  16  Aug.,  1884. 

V.  INAMCENA.  Slender,  glabrous,  or  the  peduncles  and 
petioles  obscurely  and  retrosely  hirtellous;  stems  several 
from  the  slender  roots,  but  not  much  developed,  often  1  or 
2  inches  long,  greatly  surpassed  by  the  petioles  and  leaves, 
the  plant  thus  appearing  almost  acaulescent:  leaves  round- 
ovate,  obtuse,  notably  cucullate,  lightly  crenate;  stipules 
subulate-linear,  lacerately  subpinnatifid:  flowers  seemingly 
always,  even  the  earliest,  short-pedunculate  and  apetalous, 
the  small  ovoid  capsules  deflexed. 

In  low  meadows  along  the  river  at  Gunnison,  25  July, 
n.  603.  The  species  seems  nearly  related  to  V.  retroscabra, 
though  the  leaves  are  not  only  glabrous  but  more  rounded 
and  cucullate,  while  in  the  apetalous  character  of  the 
flowers,  and  in  form  of  the  fruit,  it  connects  with  V.  physa- 
lodes.  I  also  provisionally  refer  here  a  plant  collected  by 
Mr.  Baker  at  Cameron  Pass,  northern  Colorado,  15  July, 
1896,  though  its  leaves  are  less  rounded  and  not  cucullate. 

The  three  species  next  succeeding  are  of  the  yellow- 
flowered  group  of  caulescent  violets. 

V.  GOMPHOPETALA.  Allied  to  F.  Nuttallii,  the  crown  of 
the  root-bearing  few  and  very  short  depressed  leafy  and 
floriferous  branches;  the  whole  plant  light-green,  with 
ciliate  leaves,  and  their  veins  pubescent:  leaves  from  round- 
ovate  in  the  earliest,  to  oval  and  oblong-oval  or  oval-lanceo- 
late, the  longest  1 J  inches  long,  somewhat  repand-denticulate 
or  su ben  tire,  marked  underneath  by  fine  light  almost  par- 
allel veins  or  nerves,  the  petiole  as  long  as  the  blade,  slightly 


12  PLANTS     BAKERIAN.E. 

winged  above:  peduncles  3  inches  long,  surpassing  the 
leaves:  sepals  linear-lanceolate,  acute,  glabrous:  corolla 
about  f  inch  wide,  of  rounded  circumscription,  the  petals 
cuneate-obovate,  very  obtuse  or  almost  truncate  at  the 
broad  apex,  all  brown  without,  yellow  within. 

On  open  hillsides  of  the  Grand  Mesa,  23  June,  n.  225. 

V.  PHYSALODES.  Low,  slender,  the  foliage  very  thin  and 
the  whole  plant  glabrous,  sparsely  leafy  ascending  stems 
well  developed,  2  or  3  inches  long,  short-jointed  and  with  a 
flower  in  each  axil:  leaves  from  subcordate-ovate  to  oval, 
obtuse,  almost  or  quite  entire,  f  to  1J  inches  long,  obviously 
veiny  only  beneath;  pedicels  barely  an  inch  long  in  fruit, 
slender,  deflexed:  flowers  minute,  apparently  always  apeta- 
lous;  pods  also  very  short,  subglobose  or  obovoid. 

In  thickets  along  the  Cimarron  River,  7  June,  1901,  n. 
67.  The  least  showy,  but  by  far  the  most  interesting 
violet  of  all  those  which  it  has  fallen  to  my  lot  to  describe 
as  new.  The  whole  plant  by  its  thin  entire  glabrous  leaves, 
and  numerous  fruiting  pedicels,  always  deflected  beneath 
the  leaves,  give  the  species  a  singular  likeness  to  some 
possible  small  Physalis.  Though  seeming  to  be  altogether 
apetalous,  I  nevertheless  see  in  it  a  member  of  that  yellow- 
flowered  group,  of  which  V.  NuttoMii  is  typical. 

V.  BITEBNATA.  Leafy  stem  not  well  developed  at  first,  only 
1  or  2  inches  long,  but  subradical  leaves  very  long-petioled, 
upright,  5  or  6  inches  high,  the  peduncles  of  the  few  and 
early  petaliferous  flowers  about  as  long:  leaves  very  ample, 
palrnately  or  sometimes  subpinnately  biternate,  the  primary 
divisions  broadly  cuneiform,  deeply  trifid  and  their  segments 
coarsely  and  deeply  tridentate,  all  the  segments  and  teeth 
obtuse,  the  margins  ciliolate  and  veins  pubescent  with  short 
bristly  appressed  hairs:  corolla  f  inch  broad,  all  the  petals 


POLYGONACE^E.  13 

obovate,  obtuse,  brown  without,  yellow  within,  the  keel 
nearly  twice  the  width  of  the  others:  small  apetalous 
flowers  many  along  the  at  length  well  developed  stem,  the 
capsules  succeeding  these  large,  round-obovid,  on  deflexed 
pedicels  1  or  2  inches  long. 

Related  to  V.  Sheltonii  of  the  far  Northwest,  but  very  dif- 
ferent. The  specimens,  from  two  localities,  collected  in 
June,  1901,  are  numbered  42  and  233. 

POLYGONACE.E. 

POLYGONUM  MONTANUM.  P.  Douglasii,  var.  latifolium, 
Greene,  Bull.  Calif.  Acad.  i.  125.  P.  Douglasii,  var.  mon- 
tanum,  Small,  Polyg.  118.  Low,  fastigiately  branched  from 
the  base,  3  to  6  inches  high,  the  banches  floriferous  from 
the  base,  but  the  flowers  few  among  the  proper  leaves,  most 
of  them  forming  a  mere  bracted  spike  beyond  the  foliage, 
all  the  angles  of  stem  and  branches  denticulate-scaberulous, 
and  other  parts  also  more  or  less  scabro-puberulent :  leaves 
oblong-lanceolate,  very  acute,  often  an  inch  long,  1-nerved,  the 
nerve  sharply  carinate  beneath  the  leaf:  fruiting  perianth 
subsessile  but  nodding,  its  segments  dark  green  or  purplish 
except  marginally  and  completely  enclosing  the  achene,  this 
black,  smooth  and  shining,  the  faces  obtusely  rhomboid al, 
the  cross-section  3-lobed  rather  than  triangular. 

The  above  description  is  drawn  from  a  series  of  specimens 
collected  by  Mr.  Baker  this  year  at  Marshall  Pass,  20  Aug., 
and  to  be  distributed  under  n.  893.  These  specimens 
represent  perfectly  what  I  had  in  mind  when  naming  P. 
Douglasii,  var.  latifolium.  But  in  the  lapse  of  sixteen  years, 
other  things  have  become  confused  with  this  in  my  own  and 
other  herbaria,  some  of  which  are  now  to  be  segregated. 
Habitally,  as  well  as  in  its  general  dimensions,  P.  montanum 
much  more  nearly  approaches  P.  Austinse  than  P.  Douglasii ; 


14  PLANTS     BAKERIAN^E. 

and  in  this,  as  well  as  in  a  few  but  very  constant  characters 
it  may  well  claim  specific  rank. 

P.  COMMIXTUM.  Near  the  last  but  dwarf,  2  or  3  inches 
high,  more  herbaceous  and  with  even  ampler  and  more  co- 
pious leafiness,  the  bracted  spikes  very  short  and  dense; 
leaves  and  stem  glabrous,  the  former  from  oval  and  even 
rhombic-ovate  to  oblong,  mostly  obtuse  but  with  an  abrupt 
sharp  point,  the  midvein  conspicuous,  some  secondary  veins 
more  or  less  obvious  as  diverging  from  it :  perianths  green, 
their  segments  with  white  or  purplish  margins,  more  widely 
expanding  in  flower  and  more  loosely  investing  the  longer 
and  partly  protruding  achene,  this  more  elongated  than  in 
the  last  in  proportion  to  its  thickness,  dark  and  shining. 

The  only  specimens  known  to  me  of  this  are  of  Mr. 
Baker's  collecting  as  long  ago  as  1896  in  northern  Colorado. 
One  sheet  is  from  Grizzly  Creek,  24  Aug.,  the  other  from 
Cameron  Pass,  10,000  feet  alt.,  13  Aug.,  both  called  by  him 
P.  Douglassii  latifolium.  The  most  notable  characteristic 
is  the  narrow  and  partly  exserted  achene.  This,  with  the 
dwarf  stature,  broad  venulose  leaves,  and  «he  excessive 
leafiness,  seem  to  mark  it  as  a  good  subspecies.1 

*A  study  of  the  above  Bakerian  plants  has  lead  to  the  detection  of 
another  new  species  nearly  allied,  namely  : 

P.  HOWEI.UI.  Sparingly  branched  from  the  base,  but  the  few 
branches  quite  erect  and  contiguous,  almost  equably  leafy  to  the  summit 
and  sparsely  floriferous  throughout,  more  scabrellous  than  P.  montanum 
on  all  the  angles ;  herbage  of  a  paler  and  rather  yellowish  green  :  elliptic- 
oblong  leaves  very  acute,  thinnish  and  not  inclined  to  be  revolute,  their 
thin  margins  serrulate-scabrous :  ocrese  more  scarious  and  almost  fim- 
briate  :  perianths  few,  erect  both  before  and  after  flowering,  though  not 
sessile  :  achenes  wholly  included  and  closely  invested,  very  black  and 
highly  polished,  the  face  rhombic-ovate,  i.  e.,  broadest,  and  rather 
abruptly  so,  much  below  the  middle. —  Known  to  me  only  from  Mr. 
Howells'  specimens  taken  in  the  Siskiyou  Mountains,  northern  Cali- 
fornia, 8  July,  1887,  and  distributed  for  P.  Douglasii  latifolium. 


POLYGONACE^.  15 

RUMEX  BAKERI.  A  yard  high,  the  stems  solitary  or  sev- 
eral, from  a  deep-seated  taproot  parted  below  into  coarse 
fleshy-fibrous  branches  and  with  some  more  slender  ones 
radiating  around  the  crown  of  the  main  root:  leaves,  thin, 
glabrous,  the  basal  ones  with  lanceolate-cordate  blade  8  or 
10  inches  long  on  a  petiole  nearly  as  long,  the  cauline  lance- 
linear,  short-petiolate,  those  of  the  long  and  rather  narrow 
panicle  linear-acuminate,  subsessile,  3  or  4  inches  long,  de- 
flexed:  fruit  small  (barely  two  lines  wide),  deltoid-suborbicu- 
lar,  very  obtuse,  grainless,  delicately  (but  under  a  lens  very 
distinctly)  pinnate-veined,  the  veins  running  into  a  distinct 
favose  reticulation  toward  the  margin,  but  the  margin 
itself  thin,  nerveless,  either  entire  or  obscurely  somewhat 
crenate. 

Common  in  wet  meadows  about  Gunnison,  22  August, 
n.  903,  seeming  related  to  R.  polyrhizus  of  the  more  north- 
erly mountains. 

ERIOGONUM  CHLORANTHUM.  Near  E.  flavum,  but  more 
widely  cespitose,  the  many  branches  of  the  caudex  relatively 
much  more  elongated  and  densely  invested  throughout  with 
the  remains  of  the  foliage  of  former  years;  leaves  much 
thinner,  spatulate-oblong,  obtuse,  hoary-tomentose  beneath, 
glabrate  above,  nearly  1 J  inches  long :  scapiform  peduncles 
both  slender  and  short,  little  surpassing  the  leaves,  or  even 
scarcely  equalling  them :  involucres  solitary,  many-flowered, 
the  flowers  rather  large,  the  cluster  almost  f  inch  broad: 
perianths  greenish-yellow,  the  segments  equal,  the  tube 
villous,  acute  at  base  but  not  stipitate. 

On  stony  alpine  slopes  of  Mi  Ouray,  forming  large  mats, 
20  August,  h.  853. 

ERIOGONUM  BAKERI.     Allied  to  E.  flavum,  rather  taller, 


16  PLANTS     BAKERIAN^E. 

the  branches  of  the  caudex  very  slender  and  only  loosely 
leafy,  the  leaves  thin,  the  elliptic-lanceolate  blades  J  to  1 
inch  long,  on  slender  petioles  much  longer,  white- tomentose 
beneath,  sparsely  villous  above:  scapiform  peduncles  5  to  8 
inches  high,  erect,  slender;  inflorescence  of  a  sessile  involucre 
and  1  to  3  dichotomous  peduncles  from  its  base,  the  whole 
number  of  involucres  thus  7  to  9,  all  turbinate:  perianths 
yellow,  small,  very  long-stipitate,  silky  villous,  the  inner 
segments  much  longer  than  the  outer,  all  obovate,  obtuse. 
Black  Canon,  1  Aug.,  n.  696.  Said  to  be  cespitose  in 
rather  small  tufts.  The  inflorescence  is  like  that  of  E. 
Jamesii,  though  far  less  ample;  and  the  real  affinity  is  with 
E.  flavum. 

ERIOGONUM  SALICINUM.  Allied  to  E.  microthecum  and  E. 
Simpsonii,  the  tufted  woody  stems  and  long  corymbose 
panicled  peduncles  together  more  than  a  foot  high:  blade 
of  leaf  lanceolate  or  oblong-lanceolate,  about  1 J  inches  long, 
the  petiole  little  more  than  \  inch,  stem  and  lower  face  of 
leaves  white-tomentose,  surface  glabrate:  the  long  peduncles 
perfectly  glabrous  and  very  glaucous:  corymbose  panicles 
loose,  diffuse,  8  to  10  inches  broad:  involucres  very  numer- 
ous, small  and  few-flowered,  broadly  turbinate  or  subcam- 
panulate,  5-toothed,  the  teeth  erect,  woolly  within:  perianths 
less  than  a  line  long,  segments  oblong,  obtuse,  white. 

Habitat  of  the  last;  n.  375.  The  species  would  not  easily 
be  distinguished  from  E.  Simpsonii  but  by  its  broad  and 
short  thin  leaves. 

ASCLEPIADACE^E    AND    APOCYNACE.E. 

ASCEPIAS  SPECIOSA,  Torr.  Grand  Junction,  11  June, 
n.  251. 


APOCYNACEJE.  17 

ASCLEPIAS  HALLII,  Gray.  Excellent  specimens  of  a  plant 
that  is  rare;  obtained  at  Gunnison,  25  July,  n.  595. 

APOCYNUM  AMBIGENS.  Intermediate  between  A.  andro- 
ssemifolium  of  the  East  and  A.  pumilum  of  the  Pacific  slope; 
smaller  than  the  former,  more  erect  and  more  copiously 
floriferous,  the  corollas  larger  but  still  campanulate;  follicles 
much  shorter  and  thicker. 

In  the  Black  Canon,  20  June,  n.  202;  also  at  Rogers',  14 
Aug.,  n.  799.  The  plant  is  frequent  in  several  parts  of 
Colorado,  and  has  passed  for  A.  androssemifolium;  but  both 
this  and  A. pumilum  are  better  accepted  as  fair  geographical 
subspecies. 

APOCYNUM  CANNABINUM,  Linn.  In  moist  ground  on 
Deer  Run,  10  June,  n.  80. 

APOCYNUM  LIVIDUM.  Several  feet  high,  with  the  pale 
and  glaucescent  hue  of  A.  cannabinum,  but  the  oblong- 
ovate  mucronate  leaves  much  larger  and  more  spreading- 
inflorescence  consisting,  as  in  that  species,  of  terminal  and 
naked  cymes,  but  flowers  few,  large  and  nodding,  of  a  pale 
flesh-color;  sepals  thin  and  whitish,  triangular-lanceolate, 
erect,  half  as  long  as  the  corolla,  this  campanulate,  rather 
deeply  cleft  and  with  spreading  or  recurved  segments. 

Common  on  railway  embankments  in  Black  Canon,  8 
July.  The  plant  recalls  the  Californian  A.  floribundum, 
but  differs  in  having  few  and  large  flowers  rather  than 
almost  innumerable  small  ones. 

ASPERIFOLI^. 

MERTENSIA  CONGESTA.  Tufted  stems  a  foot  high  or  less, 
stout  and  rather  succulent,  ascending;  whole  herbage  of  a

light  and  rather  vivid  green  and,  to  the  unaided  eye  seem- 
ing glabrous:  leaves  many  and  ample,  from  elongated-ovate 
to  broadly  oblong,  obtuse,  or  some  even  retuse,  the  cauline 
sessile,  the  radical  short-petioled,  all  2  to  3  inches  long, 
minutely  and  sparsely  strigose  above,  glabrous  beneath: 
flowers  many,  mostly  in  a  single  condensed  terminal  cluster, 
those  of  the  few  subterminal  branches  similarly  crowded, 
the  pedicels  very  short:  calyx  deeply  cleft  into  ovate  acute 
or  broadly  lanceolate  segments,  these  strongly  hirsute- 
ciliate  and,  in  maturity,  traversed  by  a  very  prominent 
light-colored  mid  vein:  corolla  deep-blue,  about  4  lines 
long,  the  cylindric  tube  and  campanulate  limb  about  equal: 
nutlets  acutely  ovate,  brown  when  mature  and  indistinctly 
sinuate-rugulose. 

On  Poverty  Ridge,  near  Cimarron,  13  June,  in  open 
parks,  n.  129;  also  at  Cerro  Summit,  a  smaller  plant,  n.  62. 

/^ 

MERTENSIA  LATERIFLORA.    Stems  tufted,  rather  strict  and 

very  leafy,  a  foot  high  or  more,  the  whole  plant  canescently 
silky-strigulose:  leaves  almost  crowded  on  the  stem  from 
base  to  summit,  oblong-linear,  acutish,  about  3  inches  long: 
short  cymose  flower-clusters  in  all  the -axils  from  near  the 
middle  of  the  stem,  on  pedicels  of  about  an  inch  long,  the 
lower  not  equalling,  the  uppermost  little  surpassing  the 
leaves:  calyx  small,  completely  divided  into  short-lanceolate 
scarcely  acute  segments,  these  strongly  appressed-villous  and 
ciliate:  corolla  of  a  light-blue,  small,  hardly  4  lines  long,  the 
limb  only  distinctly  shorter  than  the  tube. 

Said  to  be  common  at  9,000  feet,  above  Carson,  where  it 
forms  large  clusters,  in  flower  2  July,  n.  334.  Species  cer- 
tainly resembling  M.  linearis,  but  a  much  larger  plant  than 
that,  and  with  smaller  flowers,  the  pubescence,  however, 
being  totally  different.  The  inflorescence  is  peculiarly 
long,  narrow  and  secund. 


ASPERIFbLI^J.  19 

MERTENSIA  CYNOGLOSSOIDES.  Stems  depressed,  1J  feet 
long,  sparsely  and  very  amply  leafy,  the  herbage  delicate 
in  texture  and  of  a  vivid  green:  lowest  leaves  oblong, 
obtuse,  4  or  5  inches  long,  on  slender  petioles  of  equal 
length,  the  cauline  ovate-lanceolate,  acutish,  sessile  by  a 
subcordate-clasping  base,  these  also  3  or  4  inches  long  and 
spreading,  all  very  thin,  glabrous  beneath,  sparsely  but 
strongly  scabrous  above  and  scabrous-ciliolate:  racemes  few 
and  sparse,  long-peduncled,  the  upper  part  of  the  peduncle 
and  the  pedicels  sparsely  setose-hispid:  sepals  small,  lanceo- 
late and  ovate-lanceolate,  obtusish,  hispid-ciliolate,  other- 
wise glabrous:  corolla  light-blue,  almost  funnelform,  the 
short  and  rather  broad  tube  quite  exceeded  in  length  by 
the  campanulate  limb  into  which  it  gradually  passes:  nut- 
lets white  (perhaps  immature),  ovate,  incurved  at  summit, 
turgidly  and  very  irregularly  rugose. 

On  moist  ledges  in  the  Black  Canon,  20  June,  n.  191.  A 
remarkably  distinct  species. 

MERTENSIA  MURICULATA.  Of  the  size  of  the  last,  nearly, 
and  like  it  almost  prostrate,  but  of  firm  texture  and  glau- 
cescent:  lowest  leaves  elliptical,  the  blade  3  or  4  inches  long, 
the  petiole  shorter;  cauline  ovate  and  lance-ovate,  1J  to  2J 
inches  long,  sessile  and  partly  clasping,  all  finely  dotted 
above  with  white  pustules  developing  centrally  a  low,  stout 
white  scabrous  point,  the  margin  scabrous-ciliolate  with 
short  pustulate  hairs:  flower-clusters  in  all  the  leaf-axils, 
long-peduncled,  somewhat  crowded,  not  obviously  racemose: 
sepals  very  short,  deltoid-ovate  to  shortly  triangular-lanceo- 
late, obtuse,  setulose  on  the  back  and  strongly  hispid-ciliate: 
corolla  short  and  funnelform:  nutlets  ovate,  straight  and 
erect,  lightly  rugulose  and  minutely  tuberculate. 

Habitat  of  the  last,  and  manifestly  allied  to  it,  though  its 
firm  texture,  peculiar  pustulate  roughness,  as  well  as  the 


20  PLANTS     BAKERIAN.E. 

differences  in  inflorescence,  calyx  and  achene,  preclude  the 
confusing  of  them.     It  is  Mr.  Bakers'  n.  193.1 

OREOCARYA  HORRIDULA.  Low  inulticipitous  perennial, 
the  not  stout  rather  loosely  leafy  and  floriferous  steins  4  to 
7  inches  high,  the  whole  plant  strongly  setose-hispid :  obo 
vate  obtuse  upper  end  of  the  leaf  tapering  spatulately  to  a 
rather  long  and  narrow  petiolar  base:  racemose  short 
branches  of  the  loose  and  short  inflorescence  linear-bracted, 
but  the  bracts  barely  equalling  the  calyx;  this  in  fruit  J 
inch  long,  its  linear  and  narrow  segments  covered  with 
hispid  hairs;  corolla  white,  rather  more  than  J  inch  long, 
with  narrow  tube  and  small  spreading  limb:  nutlets  (only 
one,  usually)  narrowly  ovate,  erect  and  straight,  sharply 

1  The  characters  of  two  northwestern  Mertensias  may  here  be  given  : 
M.  SYMPHYTOIDES.  Stout,  erect,  barely  a  foot  high,  leafy  to  the 
summit  and  even  throughout  the  broad  cymose-panicled  inflorescence 
with  large  elliptic-lanceolate  acute  leaves,  these  of  a  bright  green  and 
appearing  glabrous,  but  sparsely  somewhat  tuberculate-scabrous,  espec- 
ially on  the  margin  and  the  lower  face  :  leafy  cyme  rather  lax ;  calyx 
rather  small,  deeply  cleft,  the  segments  ovate- trigonous,  acute,  glabrous 
except  as  to  the  margin,  this  very  shortly  and  almost  obscurely  scabrous- 
serrulate  :  corolla  y2  inch  long,  quite  tubular,,  the  upper  portion  quite 
cylindric  and  little  shorter  than  the  proper  tube  :  nutlets  rather  coarsely 
low-tuberculate. — Known  to  me  only  from  Emigrant  Springs,  in  the  lava 
beds  of  Modoc  Co.,  California,  where  it  was  collected  by  Mrs.  R.  M. 
Austin,  20  June,  1894. 

M.  STENOivOBA.  Size  of  the  preceding,  quite  as  leafy,  but  the  leaves 
oblong-lanceolate,  acute,  thin  and  quite  glaucous,  sparsely  scabrous, 
most  so  marginally  :  inflorescence  as  in  most  species  :  calyx  parted  into 
narrowly  lanceolate- acuminate  long  segments,  their  margins  sparsely 
setose  ciliolate :  full  grown  nutlets  scarcely  half  as  long  as  the  calyx 
and  sinuate-rugose. — Based  Mr.  Flodman's  n.  752  from  the  Bridger 
Mountains,  Montana  (as  to  the  specimens  in  my  set),  and  named  by  Mr. 
Rydberg  "M.  lanceolata,  DC."  But  it  can  have  no  intimate  connection 
with  Pursh's  type  on  which  the  species  was  founded  ;  for  that  has  a 
"  short  calyx,"  while  here  that  organ  is  rather  extremely  elongated.

margined,  the  oack  showing  a  few  irregular  rugse  and  some 
interspersed  tuberculation. 

Deer  Run,  11  June,  on  a  dry  bank;  n.  133. 

OREOCARYA  NITIDA.  Multicipitous,  slightly  woody  at 
base,  the  stoutish  stems  a  foot  high,  copiously  leafy  at  base? 
the  leaves  2  to  4  inches  long,  oblanceolate,  acute,  tapering 
to  a  long  petiolar  basal  portion,  this  again  dilated  at  the 
insertion,  both  faces  equally  silvery-silky  or  satiny,  without 
other  pubescence:  flowers  copious,  in  a  loose  open  thyrsus  of 
close  racemes:  calyx  in  fruit  J  inch  long,  the  segments 
narrowly  linear  except  at  the  broad  base,  clothed  through- 
out with  a  dense  white  villous  tomentum  and  some  inter- 
spersed setose-hispid  hairs;  corolla  J  inch  long  or  more, 
with  very  narrow  tube  abruptly  widening  to  form  a  short 
throat,  the  proper  limb  three  lines  broad,  the  color  of  the 
whole  apparently  white:  nutlets  (mostly  solitary)  large, 
ovate,  straight  and  erect,  dark-brownish,  closely  covered 
with  a  minute  whitish  almost  muricate  tuberculation. 

In  dry  stony  ground  at  Deer  Run,  11  June,  n.  95.  A 
species  noteworthy  by  the  whiteness  and  softness  of  its 
almost  satiny  indument.

22  PLANTS   BAKERIAN^. 

LABIATE. 

Family  not  strongly  represented  in  the  region,  only  the 
following  having  been  collected:  Salvia  lanceolata,  Willd.,  n. 
679;  Scutellaria  galericulata,  Linn.,  nn.  465,  552,  815; 
Mentha  Canadensis,  Linn.,  n.  547;  Dracocephalum parviflorum, 
Nutt.,  n.  599;  Agastache  urticsefolia,  Rydb.,  n.  414;  Stachys 
scopulorum,  Greene,  n.  359. 

MONARDELLA  PARVIFOLIA.  Suffrutescent  at  base,  the  many 
slender  tufted  stems  a  foot  long  more  or  less,  decumbent  at 
base,  or  more  depressed,  subcinereous-puberulent:  leaves 
mostly  ovate-lanceolate,  some  oblong-lanceolate,  all  entire, 
obtusish,  nerveless  except  as  to  the  quite  distinct  mid  vein, 
obscurely  puberulent,  closely  glandular-punctate,  small,  half 
as  long  as  the  internodes,  the  largest  seldom  J  inch  long 
including  the  short  petiole:  heads  about  }  inch  broad; 
bracts  scarcely  colored,  somewhat  strigosely  pubescent  along 
the  veins  and  densely  white-ciliate  all  around  the  margin : 
nerves  of  the  calyx  strigose-hairy,  the  short  teeth  densely 
but  shortly  setose-hirsute :  corollas  lilac-purple. 

Frequent  in  the  canon  of  the  Gunnison  near  Cimarron, 
where  it  was  first  collected  by  myself  in  1896,  and  now 
again  by  Mr.  Baker,  n.  678.  The  species  may  probably  in- 
clude the  so-called  M.  odoratissima  of  southern  Utah. 

SCROPHULARIACE^;. 

CASTILLEIA  COGNATA!  Near  C.  linaridefolia,  as  tall  and 
as  nearly  glabrous,  but  in  habit  strict,  the  leaves  both  shorter 
and  suberect  rather  than  spreading  ;  flowers  only  half  as 
long  as  in  that  species,  and  crowded,  forming  a  spike  both 
narrow  and  dense :  floral  bracts  less  deeply  trifid  and  their 
segments  very  unequal,  the  middle  one  much  the  longest, 
oblong,  obtuse,  the  others  both  short  and  narrow,  the  whole 


SCROPHULARIACE^}.  23 

bract  villous:   calyx  deeply  cleft  anteriorly;  galea  of  the 
corolla  shorter  than  the  tube. 

Border  of  a  meadow,  at  Jack's  Cabin,  7  July,  n.  616.  The 
collector  notes  that  he  saw  but  one  plant,  but  does  not  men- 
tion the  occurrence  of  other  species  of  the  genus  in  that 
vicinity.  That  the  bracts  and  calyx  are  cream-colored, 
instead  of  crimson,  is  one  of  several  hints  given  in  the 
aspect  of  the  plant,  of  a  possibly  hybrid  parentage  between 
C.  linaridefolia  and  C.  septentrionalis. 

PENTSTEMON  TEUCRIOIDES.  Suffrutescent,  low,  the  slender 
tufted  stems  erect,  2  to  5  inches  high,  leafy  throughout  and 
floriferous  from  below  the  middle,  the  whole  herbage  ciner- 
eous-pubescent: leaves  spatulate-linear,  entire,  almost  pun- 
gently  acute,  less  than  J  inch  long,  usually  exceeding  the 
interned es  :  flowers  5  or  more  in  each  subcapitate  and  short- 
pedicelled  glomerule,  all  forming  as  it  were  a  secund  raceme 
along  the  upper  one-half  and  more  of  the  stem  :  segments 
of  the  calyx  subulate-lanceolate,  acute,  entire,  wholly  herba- 
ceous: narrow  and  strongly  bilabiate  deep-purple  corolla 
about  |  inch  long,  glabrous ;  sterile  filament  bearded 
almost  from  the  base  with  orange-yellow  hairs ;  anthers 
glabrous. 

Collected  at  Sapinero,  19  June;  said  to  be  common  there, 
on  dry  ground,  n.  186.  The  specimens  are  not  well  in 
flower ;  and  the  aspect  of  the  plant,  particularly  as  to  its 
inflorescence,  is  singularly  like  that  of  a  Teucrium. 

PENTSTEMON  PROCUMBENS.  Suffrutescent,  low  and  rather 
slender,  the  older  and  more  woody  parts  of  the  branches 
prostrate  and  rooting,  the  leafy  and  floriferous  parts  assur- 
gent,  the  whole  6  to  10  inches  long;  branchlets  retrorsely 
puberulent,  as  also  the  pedicels  and  calvx.  uut  leaves  green

and  almost  glabrous,  these  many,  only  J  inch  long  bat 
rather  exceeding  the  internodes,  spatulate-obovate,  obtuse  or 
some  of  the  earliest  obcordate-notched,  entire,  those  below 
the  inflorescence  with  some  fascicled  smaller  ones  in  their 
axils,  the  upper  with  1  to  3  flowers  in  their  axils:  calyx 
parted  deeply  into  linear-liguliform  abruptly  acutish  and 
minutely  ciliolate  lobes:  corolla  elongated  and  narrow; 
anthers  glabrous. 

Forming  large  mats  on  open  slopes  at  Keblar  Pass,  7 
Aug.,  n.  733.  The  species  is  related  to  P.  csespitosus.  It 
may  possibly  be  identical  with  Gray's  so-called  var.  suffru- 
ticosus  of  that  species;  but  of  that  I  have  seen  no  specimens, 
and  the  description  is  insufficient  for  the  identification  of  a 
species. 

COMPOSITE. 

SENECIO  CONTRISTATUS.  Stems  several,  stout,  erect,  2  feet 
high  or  less,  leafy  up  to  the  simple  raceme  of  several  large 
nodding  rayless  heads:  lowest  leaves  with  an  elliptic  blade 
3  inches  long  and  a  broadly  winged  petiole  half  as  long, 
the  cauline  more  lanceolate,  subsessile  or  sessile,  all  closely 
callous-denticulate,  scaberulous  between  the  callosities,  other- 
wise glabrous,  like  all  other  parts  of  the  plant:  heads  broadly 
campanulate,  }  inch  high,  the  lanceolate  acute  bracts  of  the 
involucre  of  a  very  dark  red-brown,  the  inner  ones  with 
obvious  yellow  scarious  margin:  rays  none, disk  light-yellow. 

In  small  clumps  on  open  ground  at  Keblar  Pass,  14  Aug., 
n.  787.  An  interesting  addition  to  that  small  group  of 
Rocky  Mountain  species  marked  with  few  and  large  rayless 
heads.  This  one  is,  however,  more  nearly  allied  to  the 
southern  S.  Rusbyi  than  to  its  near  neighbor,  8.  scopulinus. 

SENECIO   PYRRHOCHROUS.     Erect,   stoutish,  2    feet   high, 


COMPOSITE.  25 

glabrous,  rather  copiously  leafy  toward  the  base,  remotely 
bracted  above  the  middle :  lower  leaves  oval,  obtuse,  coarsely 
but  rather  lightly  crenate,  2  or  3  inches  long,  on  slender 
petioles  of  4  or  5  inches,  the  middle  cauline  lyrate-pinnatifid 
and  the  bracts  above  them  similar  but  reduced  and  sessile: 
terminal  cymose  corymb  like  that  of  S.  aureus,  but  the  heads 
larger,  the  campanulate  involucres  4  or  5  lines  high:  flowers 
of  both  disk  and  ray  fiery-red. 

Common  in  meadows  at  Jack's  Cabin,  25  July,  n.  612. 
A  very  handsome  subspecies  of  S.  aureus,  with  large  leaves 
very  regularly  crenate  all  around  the  margin;  the  flowers 
of  the  richest  fire-red.  Mr.  Baker's  n.  348  from  meadows 
near  Sargent,  not  yet  in  full  flower  at  date  of  July  5,  must 
also  be  referred  here,  though  in  some  of  these  specimens 
the  lowest  leaves  are  subcordate,  and  many  of  them  almost 
entire. 

SENECIO  LAPATHIFOLIUS.  Stems  clustered,  stout,  more  or 
less  decumbent,  a  foot  high  or  more,  leafy  throughout,  the 
herbage  deep-green  and  glabrous:  leaves  4  to  6  inches  long, 
lanceolate,  acute,  sessile  by  a  broad,  or  sometimes  taper- 
ing half-clasping  base,  undulate,  more  or  less  obviously 
denticulate:  heads  5  to  10,  large,  the  campanulate  invo- 
lucres more  than  J  inch  high,  mostly  arising  singly  from 
the  axils  of  the  leaves,  these  on  very  long  peduncles,  the 
whole  forming  a  loose  subcorymbose  panicle;  bracts  of  invo- 
lucre lanceolate  (rather  broadly  and  triangularly  so):  rays 
narrow,  about  as  long  as  the  bracts:  achenes  striate,  glabrous. 

On  the  divide  between  Ouray  and  Telluride,  10  Aug.,  n. 
738.  In  some  ways  suggestive  of  S.  crassulus,  and  doubtless 
allied  to  it,  but  in  character  very  different.  The  long  pedun- 
cles are  peculiarly  turbinate-thickened  under  the  involucre, 
and  the  whole  plant  appears  to  be  much  more  succulent 
than  S.  crassulus.

vate-spatulate  obtuse  mostly  5-toothed  (often  3-toothed,  or 
even  quite  entire)  blades  commonly  about  as  long  as  the 
petioles;  growing  parts  of  the  plant  hoary- tomentulose,  the 
older  foliage  glabrate :  peduncles  with  one  or  more  narrow

ferent habit  and  foliage. 

HELIANTHUS  FASCICULARIS.  Perennial,  rather  slender, 
tbe  solitary  stem  2  or  3  feet  high  from  a  fascicle  of  small 
fusiform  tuberous  roots,  glabrous  or  sparsely  pubescent,  glau-

TETRANEURIS  INTERMEDIA.  Perennial,  csespitose,  the 
slender  peduncles  6  to  8  inches  high,  rarely  bractless, 
usually  with  one  or  more  leafy  bracts  below  the  middle,  not

PSILOSTROPHE  BAKERi.  Herbaceous,  apparently  perennial, 
much  branched,  4  to  8  inches  high,  the  branches  at  earliest 
flowering  not  much  exceeding  the  large  spatulate-obovate  or

of  fruit. 

HYMENOPAPPUS  OCHROLEUCUS.  Perennial,  the  stoutish 
caudex  branching,  each  branch  with  a  tuft  of  petiolate 
leaves  and  a  subscapiform  though  branched  and  corymbose 
stem  12  to  18  inches  high;  herbage  white-floccose  when 
very  young,  the  stem  and  fully  developed  foliage  more  or 
less  completely  glabrate:  principal  leaves  4  or  5  inches  long, 
pinnate  or  more  or  less  completely  bipinnate,  i.  e.,  some  of 
the  segments  entire,  only  those  below  the  middle  of  the

ARTEMISIA  BAKERI.  Allied  to  A.  Mexicana  but  more 
slender,  and  with  the  tufted  stems  decumbent  or  depressed 
and  also  rather  loosely  branching:  foliage  rather  sparse, 
green  and  glabrous  above,  white-torn entose  beneath,  the 
lower  leaves  with  few  and  rather  remote  pinnate  segments, 
those  of  the  branchlets  entire,  all  linear  or  with  linear  seg- 
ments, the  margins  narrowly  re  volute:  heads  in  an  ample 
and  loose  panicle,  many  of  them  short-pedicellate,  campanu- 
late,  the  outer  bracts  short,  herbaceous,  acute,  the  inner 
obtuse  and  largely  scarious,  all  somewhat  arachnoid- 
canescent. 

This  species,  very  well  marked  as  to  habit,  was  first  col- 
lected by  myself,  in  the  canon  of  the  Gunnison,  near 
Cimarron,  Colorado,  in  August  of  1896.  Mr.  Baker  now 
distributes  it,  and  from  the  original  station,  or  near  it, 
under  n.  698. 

ERIGERON  SIMULANS.  Near  E.  pumilus  and  of  the  same 
size  and  habit,  the  many  short  stems  crowning  the  taproot 
almost  or  altogether  herbaceous;  the  spatulate-linear  leaves 
strongly  and  very  stiffly  hispid-ciliate  from  the  base  to  the 
middle,  the  upper  portion  (or  proper  blade)  with  a  finer 
strigose  hairiness  closely  appressed:  pedunculiform  mono- 
cephalous  branches  sparingly  leafy  below,  slender  and 
naked  under  the  involucre,  this  green  and  as  if  glabrous 
to  the  unaided  eye,  but  its  outermost  bracts  sparsely  bristly-

1901,  C.  F.  Baker,  n.  40.  The  plant  so  closely  simulates, 
habitally,  the  common  but  always  more  northerly  E.pumilus, 
that  but  for  its  very  remarkable  double  pappus  it  would 
have  been  let  pass  for  that  species.  But  upon  examination 
its  pubescence  is  of  another  character,  and  the  whole  plant 
is  greener  and  more  slender. 

PLANTAGINACE^;. 

PLANTAGO  RETRORSA.  Perennial,  of  the  size  and  with  the 
habit  of  P.  eriopoda,  and  with  even  a  closely  similar  pubes- 
cence^ but  wholly  wanting  the  fuscous  woolliness,  which  so 
conspicuously  marks  that  species,  the  leaves  not  entire  but 
coarsely  though  sparsely  runcinate-toothed  below  the  mid- 
dle :  sepals  much  more  herbaceous,  and  capsules  more  elon- 
gated; seeds  elliptic-oblong. 

Abundant  in  alkaline  meadows  at  Doyle's,  28  June,  n. 
627.  Excellently  marked  by  the  four  characters  indicated, 
as  distinct  from  the  kindred  species,  with  which  it  may 
have  been  confounded,  if  before  collected  ;  but  the  plant  is 
wholly  new  to  me.1 

NYCTAGINACE.E.  ' 

ABRONIA  BAKERI.  Allied  toA.fragrans,  but  much  smaller, 
and  suffrutescent,  the  stems  and  branches,  both  the  woody 

1iP.  SHASTENSIS.  Also  allied  to  P.  eriopoda,  and  with  definite  traces 
of  its  basal  woolliness,  but  leaf -outline  and  leaf -texture  very  different,  all 
being  comparatively  thin,  not  at  all  ceriaceous,  and  the  outline  distinctly 
obovate,  the  whole  margin  apt  to  be  more  or  less  repand-toothed :  spikes 
relatively  short,  and  much  more  dense  than  in  P.  eriopoda;  capsules  almost 
globose  and  not  exceeding  but  even  quite  included  within  the  calyx,  the 
sepals  of  which  are  largely  herbaceous,  and  their  narrow  scarious  margins 
distinctly  ciliolate  all  around  :  seeds  oval. — Species  known  to  me  only  as 
collected  by  myself  on  the  plains  of  Shasta  River  in  Northern  California, 
twenty-five  years  since.  They  were  distributed  for  P.  eriopoda,  but  are 
now  seen  to  represent  something  very  distinct.

and  the  herbaceous  ones,  glabrous  and  very  glaucous:  leaves 
much  smaller  than  in  A.frograns,  subcordate-orbicular  to 
oval,  very  obtuse,  usually  about  an  inch  long,  on  petioles 
somewhat  longer  or  shorter:  flower  smaller  than  in  A.  fra- 
grans,  the  perianth-limb  apparently  funnelfrom  rather  than 
rotate:  fruits  scabrous  on  the  sides,  roughish-tomentulose  at 
summit. 

This  species,  easily  distinguished  from  the  northern  and 
and  true  A.  fragrans  (a  large  perennial,  wholty  herbaceous) 
by  its  small  size,  suffrutescent  habit,  white  stems  and  total 
lack  of  clamminess,  is  well  represented  in  the  following 
numbers:  13,  obtained  at  Montrose,  best  showing  the  half- 
shrubby  growth ;  89,  from  Deer  Run,  somewhat  larger,  and 
92,  from  Grand  Junction;  this  last,  at  least  in  my  set,  is  a 
young  plant,  flowering  perhaps  the  first  year  from  the  seed, 
and  thus  exhibiting,  naturally,  no  sign  of  the  ultimate 
woodiness  of  the  stem. 

ALLIONTA  ROTUNDIFOLIA.  About  a  foot  high,  the  stoutish 
clustered  stems  ascending,  densely  crinite-hirsute  as  to  the 
lower  and  shorter  internodes,  the  upper  portions,  as  well  as 
the  lower  face  of  the  uppermost  leaves  more  loosely  and 
hispidly  hirsute:  lowest  leaves  suborbicular,  obtuse,  about 
1 J  inches  long,  the  upper  larger,  sometimes  round-ovate,  all 
more  or  less  woolly-ciliolate:  flowers  and  fruits  not  seen. 

Obtained  at  Swallow's,  between  Pueblo  and  Canon  City, 
1  June,  n.  3.  The  specimens,  though  not  yet  in  flower, 
exhibit  in  their  peculiar  foliage  and  pubescence  characters 
sufficient  for  the  establishment  of  a  species.  The  inflores- 
cences are  clustered,  and  arise  from  the  axils  of  only  the 
uppermost  leaves.

racemes  short  and  few-flowered,  even  subcapitate,  the 
corollas  large;  calyx  villous,  its  triangular  teeth  half  as 
long  as  the  tube:  pods  about  3  inches  long,  ascending, 
straight,  appressed-pubescent. 

At  Marshall  Pass,  common  in  open  places  among  the 
pine  woods,  19  July,  n.  485;  flowering  specimens  only;  but 
the  fruiting  specimens,  from  precisely  the  same  locality, 
were  obtained  by  myself,  4  Sept.,  1896,  and  have  been  kept 
ever  since,  under  the  above  name  as  a  new  species,  awaiting 
flowering  specimens. 

THERMOPSIS  STRICTA.  Much  taller,  even  1J  feet  high  in 
flower,  very  strict,  and  'with  a  long  interrupted  raceme  of 
smallish  flowers  of  which  the  lowest  are  subverticillate: 
mature  leaflets  If  to  2J  inches  long,  mostly  oblong  or  ellip- 
tical, some  of  the  largest  inclining  to  oblanceolate,  glabrous 
above,  sparsely  pubescent  beneath;  ovate  stipules  1  to  2 
inches  long:  calyx  canescently  villous,  its  teeth  narrower, 
more  than  half  the  length  of  the  tube:  pods  very  erect,  2 
inches  long  or  more,  villous- torn  en  tose. 

In  meadows  at  Sapinero,  19  June,  n.  173,  in  flower;  also

1  T.  ANGUSTATA.  Two  feet  high  and  somewhat  bushy  by  several  well 
developed  leafy  sterile  branches,  but  only  the  main  stem  bearing  flowers  : 
leaflets  about  2  inches  long,  elliptical,  deep-green,  villous-pubescent 
beneath  (as  also  the  stem),  but  glabrous  above;  stipules  small  and 
narrow,  barely  i  inch  long,  or  even  less,  and  lanceolate  :  calyx  and  pods 
hoary-tomentose,  the  latter  about  2  inches  long,  strictly  erect. — Known 
only  as  collected  by  myself,  at  Star  Valley,  in  the  foothills  of  the  Ruby 
Mountains,  Nevada,  20  July,  1896.  The  specimens  are  in  fruit  only,  but 
by  the  remarkably  narrow,  and  almost  exactly  elliptical  foliage,  and  the 
tomentose  pods,  a  marked  species  is  indicated.

leaflets  7  or  8,  lance-elliptical,  acute,  the  largest  2  inches 
long;  raceme  sessile,  6  inches  long,  rather  dense,  all  the 
flowers  scattered,  rather  large;  stout  pedicels,  and  short  gib- 
bous calyx  scarcely  more  velvety  than  the  rachis;  corolla 
wholly  dark  blue-purple,  the  petals  subequal,  the  not 
strongly  falcate  keel  densely  woolly-ciliate  throughout : 
pods  more  than  an  inch  long,  quite  broad,  velvety-tomen- 
tose. 

At  Cedar  Edge,  24  June,  n.  246. 

LUPINUS  DICHROUS.  Size  and  habit  of  the  last,  with 
similar  though  somewhat  larger  foliage,  the  pubescence  both 
shorter  and  more  scanty,  perhaps  best  described  as  silvery-

canescent;  raceme  short-ped uncled,  less  elongated,  open  and 
subverticillate;  pedicels  and  short  gibbous  calyx  velvety: 
corolla  at  first  white,  the  banner  only  at  length  changing 
to  reddish-purple,  this  rather  shorter  than  the  other  petals; 
keel  rather  broadly  lunate  and  not  long-pointed,  strongly 
woolly-ciliate  throughout:  pods  oblong-linear,  1J  inches 
long,  silky-tomentose,  5-seeded  ;  seeds  flat,  white. 

Also  at  Cedar  Edge,  24  June,  n.  249;  the  strictly  two- 
colored  rather  large  corollas  rendering  the  plant  very 
attractive. 

LUPINUS  AMPLUS.  Stems  clustered,  stout,  3  feet  high, 
very  leafy  with  leaves  of  the  largest  dimensions,  the  thin 
elliptic-lanceolate  acute  leaflets  about  10  and  3  to  5  inches 
long,  green  and  glabrous  above,  sparsely  appressed-silky- 
hairy  beneath  and  more  strongly  so  on  the  margin;  the 
stem  and  peduncles  villous:  raceme  sessile,  10  inches  long, 
both  broad  and  rather  dense,  nowhere  subverticillate: 
pedicels  J  inch  long  or  more,  densely  hirsute,  as  also  the 
short  calyx:  corolla  of  the  largest,  j  inch  long;  banner 
shortest,  dark-purple;  wings  violet,  .conspicuously  striate- 
veined  with  purple;  keel  falcate,  slender-pointed,  hirtellous- 
ciliate  above  the  middle:  pods  not  seen,  but  ovaries  silky- 
tomentose. 

At  Cerro  Summit  above  Cimarron,  17  June,  n.  164.  Very 
large  and  showy,  recalling  L.  magnus  of  the  Californian  sea- 
board, almost  as  large,  but  not  succulent;  and  quite  as 
distinct  from  the  far-northwestern  L.  polyphyllus. 

LUPINUS  LEPTOSTACHYUS.  Clustered  stems  stout,  very 
erect,  2  feet  high  or  more,  with  relatively  small  leaves  and 
the  smallest  ot  flowers  in  very  long  racemes:  leaflets  about 
9,  oblong-linear,  abruptly  acute,  unequal,  the  longest  1J
